      Intended useThe Calbiochem® MMP-1 ELISA is a non-isotopic immunoassay for the in vitro quantitation of human MMP-1 protein in tissue culture media and serum.
      BackgroundMatrix metalloproteinase-1 (MMP-1; interstitial collagenase) is an important member of the MMP family of neutral endopeptidases responsible for the degradation of the extracellular matrix (ECM) and is involved in tumor invasion and metastasis. MMP-1 is a collagenase with substrate specificity for type I, II, III, VII, VIII and X collagens and gelatin. The proteolytic degradation of the ECM is an important aspect of many physiological and pathological conditions associated with alterations in connective tissue proteins such as embryo implantation, morphogenesis, wound healing, ovulation, cell migration, tissue involution, angiogenesis, and tumor invasion. MMP-1 is secreted from stimulated macrophages, neutrophils and transformed cells in a latent form. In fact all MMPs, except membrane-type metalloproteinases, are secreted as inactive zymogens into the extracellular matrix, where subsequent activation results in cleavage of the proenzymes into the active species. The presence or absence of activators and the binding of tissue inhibitors of metalloproteinases (TIMPs) maintains strict control on the activation of such enzymes in the extracellular space. The TIMP family has four members: TIMP-1, TIMP-2, TIMP-3, and TIMP-4. Binding of the TIMPs to their specific MMPs results in efficient inhibition of enzymatic activity of MMPs. The MMP-1 protein can cleave collagen helices to yield characteristic one-quarter-three-quarter products. It is secreted as a latent proenzyme of 52 kDa that is N-glycosylated to a minor form of 57 kDa. MMP 1 can be proteolytically processed to the 46/42 kDa active forms in vitro by proteinases (e.g., plasmin, trypsin), organomercurial compounds (e.g., 4-aminophenylmercuric acetate, APMA) and in vivo by plasmin and MMP-3 (stromelysin). Although sequences are conserved across species and there is >50% homology among enzymes, the collagenases are distinguished from other MMPs by their domain structure and substrate specificity. MMP-8 (neutrophil collagenase) has been described to share close homology with MMP-1.
      Principles of the assayThe MMP-1 ELISA is a "sandwich" enzyme immunoassay employing two monoclonal antibodies. A monoclonal antibody, specific for human MMP-1 protein, has been immobilized onto the surface of the plastic wells provided in the kit. The sample to be assayed (test samples and standards) are pipetted into the wells and any human MMP-1 protein present binds to the capture antibody. Unbound material is washed away and a monoclonal, horseradish peroxidase (HRP)-conjugated anti-MMP-1 antibody is added to the wells. Following this incubation and a wash step, a chromogenic substrate is added to the wells. The horseradish peroxidase catalyses the conversion of the chromogenic substrate tetra-methylbenzidine (TMB) from a colorless solution to a blue solution (or yellow after the addition of stopping reagent), the intensity of which is proportional to the amount of human MMP-1 protein in the test sample. The colored reaction product is quantified using a spectrophotometer.
      Quantitation is achieved by the construction of a standard curve using known concentrations of human MMP-1 protein (provided lyophilized). By comparing the absorbance obtained from a sample containing an unknown amount of human MMP-1 protein with that obtained from the standards, the concentration of human MMP-1 protein in the test sample can be determined.
      Materials providedStandards should be assayed in duplicate. A standard curve must be performed on the same plate and at the same time as the samples. The MMP-1 ELISA contains one plate with sufficient reagents to run 96 tests (including standard curves).

      • COATED 96-WELL PLATE (Kit Component No. JA1625-1EA): 96 removable wells coated with mouse anti-human MMP-1 monoclonal antibody.
      • ProMMP-1 PROTEIN STANDARD (Kit Component No. JA1629-1EA): 3.6 ng of human proMMP-1 lyophilized.
      • MMP-1 CONJUGATE (Kit Component No. JA1626-12.6ML): 0.6 ml of anti-MMP-1 monoclonal antibody conjugated to horseradish peroxidase (HRP). Dilute with 12 ml of Assay Buffer.
      • ASSAY BUFFER (Kit Component No. JA1628-1EA): 2 bottles of sodium phosphate buffer containing BSA, lyophilized. The contents of each bottle will be reconstituted in 20 ml of deionized or distilled water.

      • PLATE COVER: 1 lid to cover plate during incubations.
      Materials Required but not provided• 2-20 µl, 20-200 µl and 200-1000 µl precision pipettors with disposable tips; 1 ml, 5 ml, 10 ml and 25 ml pipettes for reagent preparation.
      • Wash bottle or multi-channel dispenser for washing.
      • Deionized or distilled H2O.
      • Graduated cylinder (500 ml)
      • 12 mm x 75 mm polypropylene test tubes.
      • Spectrophotometer capable of measuring absorbance in 96-well plates using dual wavelength of 450/540 nm or 450/595nm.
      Precautions and recommendations• Store unopened kit at -20°C. Do not expose reagents to excessive light.
      • Do not mix reagents from different kits.
      • Do not use metallic labware with the enclosed reagents. Color Reagent may react with the metal labware.
      • Bring all reagents to room temperature before use. Gently stir the reagents prior to use.
      • Wear disposable gloves and eye protection.
      • The Stop Solution is an acid solution. Exercise caution when handling this solution.
      • Use only the wells provided with the kit.
      • Do not make direct contact with kit buffers and reagents. Do not mouth pipette or ingest any of the reagents.
      • Do not smoke, eat, or drink when performing the assay or in areas where samples/reagents are handled.
      • Samples may be contaminated with infectious agents. Do not ingest, expose to open wounds, or breathe aerosols. Dispose of samples properly.
      • It is recommended that samples falling above the range of the standard curve be diluted to fall within the mid-range of the curve. For samples that have been diluted, the MMP-1 protein concentration must be multiplied by the dilution factor (e.g. if samples are diluted five fold, then the MMP-1 protein concentration value obtained from the standard curve must be multiplied by five).
      • Do not use samples that have gone through multiple freeze/thaw cycles. If samples are to be stored at -20°C, it is recommended to divide samples into working aliquots and store at -20°C.
      • DO NOT USE PLASMA SAMPLES COLLECTED BY EDTA, HEPARIN OR CITRATE. These reagents can change the antibody reactivity to MMP-1 protein.
      • Avoid adding reagents to the side of the wells. Add samples directly to the center of the well.
      • Add Stop Solution in same well order as the Substrate Solution.
      • Change pipette tips between different sample additions to avoid cross-contamination.
      Preparation• Cell Culture Medium: Centrifuge all samples to remove particulate material before assaying. Assay immediately or aliquot and store samples at ≤-20°C. Avoid freeze/thaw cycles. • Serum: Use a serum separator tube (SST) and allow blood samples to clot for 30 min. Once clotted, samples are centrifuged at 1000 x g for 10 min. Carefully remove serum and assay immediately or aliquot and store serum samples at ≤-20°C. Avoid freeze/thaw cycles. Samples found to contain greater than 3.6 ng/ml MMP-1 (i.e., outside the range of the standard curve) must be diluted with Assay Buffer (provided), so that the MMP-1 concentration falls within the range spanned by the standard curve, and assayed again.
      Reagent preparationNote: Bring all reagents to room temperature before use. • Assay Solution: Reconstitute each bottle of Assay Buffer in 20 ml of deionized or distilled water. The reconstituted Assay Buffer may be stored at 4°C for up to 1 month. • Wash Buffer: Warm the Wash Buffer Concentrate to room temperature before use (this will dissolve any crystals, which may be present in the concentrate). Mix 20 ml of Wash Buffer Concentrate with 480 ml of deionized or distilled water to provide enough 1X wash buffer (500 ml) for one plate. The diluted Wash Buffer may be stored at 4°C for up to 1 month. • MMP-1 Conjugate: Add 12 ml of Assay Buffer to the MMP-1 Conjugate. The diluted MMP-1 Conjugate may be stored at 4°C for up to 1 week. • MMP-1 Standard: Reconstitute the MMP-1 Standard with 1 ml of deionized or distilled water and allow to mix gently for 15 min before making serial dilutions. This reconstitution makes a stock solution of 3.6 ng/ml. Prepare serially diluted standards just before use as follows: • MMP-1 Standard Dilutions: Note: Use polypropylene tubes. To make serial dilutions of the standard, obtain 5 tubes and label them 1.8, 0.9, 0.45, 0.23, 0.11 ng/ml. Add 250 µl of Assay Buffer into each tube. The undiluted standard (3.6 ng/ml) serves as the high point of the standard curve. Assay Buffer alone acts as the zero standard (0 ng/ml). Remove 250 µl from the undiluted, reconstituted standard vial (3.6 ng/ml) and add it to the first tube (1.8 ng/ml). Mix gently before the next transfer. Remove 250 µl from the first tube (1.8 ng/ml) and add it to the second tube (0.9 ng/ml) and mix gently. Repeat this procedure until you reach the fifth tube (0.11 ng/ml). Any remaining undiluted standard (3.6 ng/ml) may be stored for 1 week at 4°C. Serially diluted standards should be discarded after one use.
      Detailed protocolThe MMP-1 ELISA is provided with removable wells so the assay can be carried out on separate occasions. Since conditions may vary, a standard curve MUST be determined each time the assay is performed. Standards and test samples should be assayed in duplicate. Disposable pipette tips and reagent troughs should be used for all transfers to avoid cross-contamination of reagents or samples.
      Note: Bring all reagents to room temperature before use.
      1. Prepare all samples, controls, standards and reagents as described in the previous sections.
      2. Remove the appropriate number of wells from the pouch and place them into the empty well holder. Return any unused wells to the original pouch, refold, seal and store at 4°C. Unused wells may be stored at 4°C for up to 1 week.
      3. Pipette 100 µl of Standard or Sample into each well.
      4. Cover the plate with the lid provided and incubate the plate at room temperature for 2 h without shaking.
      5. Aspirate each well and wash wells 5 times with 1X Wash Buffer making sure each well is filled completely. Each well is washed by filling with 400 µl of 1X Wash Buffer (using a multichannel pipette, automatic plate washer or wash bottle). It is essential to completely remove the Wash Buffer after each step and to ensure that the wells do not contain any buffer after the last wash. This can be achieved by inverting the plate and tapping it on paper towels.
      6. Pipette 100 µl of the MMP-1 Conjugate into each well. Cover the plate with the lid provided and incubate the plate at room temperature for 1 h without shaking.
      7. Aspirate each well and wash wells 5 times with 1X Wash Buffer making sure each well is filled completely, following procedure as outlined in Step 5.
      8. Pipette 100 µl of Substrate (TMB) Soluble into each well. Cover the plate with the lid provided and incubate the plate in the dark at room temperature for 30 min without shaking.
      9. Stop the reaction by adding 100 µl of Stop Solution (2.5 N Sulfuric Acid) into each well in the same order as the previously added Color Reagent. If color change does not appear uniform in the well, gently tap the plate frame to ensure thorough mixing.
      10. Measure absorbance in each well using a spectrophotometric plate reader at dual wavelengths of 450/595 nm (540 nm can be used as an alternative reference wavelength). If wavelength reference is not available, subtract the readings at 595 nm or 540 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate. Wells must be read within 30 min of adding the Stop Solution.
      Note: Samples, which give values higher than the highest standard should be diluted with the Assay Buffer and re-evaluated in the assay.
      Calculations1. Average the duplicate absorbance values for the standards (including the zero) and all samples. Subtract the average zero standard absorbance value from each averaged standard and sample value. 2. On graph paper, plot the mean absorbance values (Abs) for each of the standards on the Y-axis, versus the concentration of each standard (ng/ml) on the X-axis. Alternatively, the data may be linearized by plotting the log of MMP-1 concentration versus the log of the Abs and the best fit line can be determined by regression analysis. 3. Determine the concentration of unknowns by interpolation from the standard curve. There are a variety of microplate reader software packages available (Softmax, Molecular Devices Corporation, Menlo Park, CA; KinetiCalc, BioTek Instruments, Inc. Winooski, VT) for analysis of microplate data, which simplify this process. Interpolation of the sample values from the standard graph will represent ProMMP-1 concentrations since ProMMP-1 protein is used as the standard for this ELISA. 4. For samples that have been diluted, the MMP-1 protein concentration must be multiplied by the dilution factor (e.g. if samples are diluted five fold, then the MMP-1 protein concentration value obtained from the standard curve must be multiplied by five).
      Standard curveA typical standard curve generated by this kit is shown below. The standard curve is for demonstration only and should not be used for data extrapolation purposes. Data should be extrapolated from standard curves run within, and in conjunction with the test samples. A standard curve should be run in duplicate each time an assay is performed.

      Figure 1: MMP-1: Sample Standard Curve
      Example dataExpected Values: Serum samples from thirty-six healthy individuals were evaluated for the presence of MMP-1 using the MMP-1 ELISA.

      Table 1: Expected Values
      Sensitivity0.023 ng/ml
      Sensitivity NotesThe minimum dose of MMP-1 protein as detectable in this assay is typically less than 0.023 ng/ml. This value is calculated by adding two standard deviations to the mean optical density of 30 zero standard replicates and calculating the corresponding concentration.

      Precision

      Table 2: Intra-Assay Precision

      This reflects the precision within an assay. Serum samples containing three known concentrations of MMP-1 protein were analyzed 10 times each, in replicates of two in a single assay to assess intra-assay precision. Cell culture media samples containing a known concentration of MMP-1 protein were analyzed 10 times in replicates of two in a single assay to assess intra-assay precision.


      Table 3: Inter-Assay Precision

      This reflects the precision between assays. Repeated measurements of serum samples containing three known concentrations of MMP-1 protein were analyzed in replicates of two in eight separate assays to assess inter-assay precision. Repeated measurements of cell culture media samples containing a known concentration of MMP-1 protein were analyzed in replicates of two in eight separate assays to assess inter-assay precision
      RecoveryThe average % recovery of MMP-1 protein, spiked to five levels in two serum and one cell culture media samples, throughout the range of the assay in various matrices was evaluated.

      Table 4: Recovery
      LinearityThe assay linearity was assessed using two serum and one cell culture media samples spiked with known concentrations of MMP-1 protein in various matrices and diluted with Assay Buffer. The samples generated values, which fell within the dynamic range of the assay. The linearity assay results are shown below:
