      BackgroundTissue-type plasminogen activator (t-PA) is a serine protease found in blood plasma, serum, other body fluids, and tissues. It converts the inactive proenzyme plasminogen to the active protease plasmin. Plasmin degrades the fibrin that makes up blood clots in a process known as fibrinolysis, which leads to the dissolution of the clot. Plasminogen activation is also implicated in the metastatic spread of malignant cells and in tissue remodeling. Fibrin has been shown to accelerate the conversion of plasminogen to plasmin, which is mediated by t-PA. Through this pathway fibrin promotes its own degradation. Inhibitors to t-PA have been found in blood preparations, cell culture media, and tissues. Plasminogen activator inhibitors -1 and -2 react with t-PA to form inactive complexes and the availability of free active t-PA is regulated through this interaction. Altered levels of soluble t-PA have been implicated in the progression of Graves disease, liver disease, diabetic retinopathy, cardiovascular disease, thrombosis, myocardial infarction, and stroke.
      Principles of the assayThe Calbiochem® brand t-PA ELISA kit is suitable for quantitative detection of soluble human Tissue-type plasminogen activator levels in cell culture supernatants, human serum, plasma, urine, or other body fluids.

      Precautions and recommendations• As conditions may vary from assay to assay a standard curve must be established for every run.
      • Bacterial, fungal, or cross contamination of samples or reagents may cause erroneous results.
      • While disposable pipette tips, flasks, or glassware are preferred, reusable glassware must be thoroughly washed and rinsed prior to use.
      • Insufficient washing at any stage of the procedure will result in either false positive or false negative results. Completely empty and fill wells as indicated for each wash cycle and do not allow wells to dry out at any time.
      • The limit of detection of t-PA defined as the analyte concentration resulting in an absorption significantly higher than that of the dilution medium (mean plus three standard deviations) was determined to be 8 pg/ml (mean of 6 independent assays).
      • When a panel of 7 sera from healthy blood donors was tested for t-PA the detected t-PA levels ranged between 500 and 5500 pg/ml with a mean level of 2060 pg/ml.
      PreparationRemove serum or plasma from the clot or red cells, as soon as possible after clotting and separation. Note: samples containing a visible precipitate must be clarified prior to use. Do not use extensively hemolyzed or lipemic specimens. Store all samples at -20°C. Allow to come to room temperature before use. Avoid freeze/thaw cycles.
      Reagent preparation1. Add distilled or deionized water to 50 ml Wash Buffer Concentrate for a final volume of 1,000 ml. Mix gently to avoid foaming and transfer to a clean wash bottle. Bacterial or fungal contamination of samples or reagents may cause false results. The pH of the final solution will be 7.4. Wash Buffer is stable for 30 days at 2° to 25°C.
      2. Mix the contents of the Assay Buffer Concentrate and add to 95 ml distilled or deionized water. Mix gently to avoid foaming. Assay Buffer is stable for 30 days at 4°C.
      3. The HRP-conjugated anti-t-PA should be diluted 1:100 as needed with Assay buffer and used within 30 min of dilution.
      4. Reconstitute t-PA standard with distilled water as stated on the label of the standard as needed and mix gently.
      Detailed protocol1. Mix all reagents gently to avoid foaming before use.
      2. Determine the number of Anti-t-PA Coated Plate required to test the desired number of samples and the appropriate number of blanks and standards. Each sample, standard, blank, and optional control sample should be assayed in duplicate. Remove extra Anti-t-PA Coated Plate (16 wells per strip) coated with polyclonal antibody (sheep) to human soluble t-PA from holder and store in sealed foil bag with the desiccant at 4°C.
      3. Wash the Anti-t-PA Coated Plate twice with approximately 300 µl Wash Buffer per well with thorough aspiration of microwell contents between washes. Please note that insufficient washing at any step in the assay will result in false results. Completely empty wells before each wash. Take care not to scratch the surface of the microwells. After the last wash, empty wells and tap Anti-t-PA Coated Plate on absorbent pad or paper towel to remove excess buffer. Use the Anti-t-PA Coated Plate immediately after washing or place upside down on a wet absorbent paper for not longer than 15 min. Do not allow wells to dry.
      4. Add 100 µl of Sample Diluent in duplicate to all standard wells. Prepare standard dilutions by pipetting 100 µl of the t-PA standard, in duplicate, into wells A1 and A2. Mix the contents of wells A1 and A2 by repeated aspiration and transfer 100 µl to wells B1 and B2, respectively. Take care not to scratch the inner surface of the wells. Continue this procedure five times, creating two rows of t-PA standard dilutions ranging from 16 to 1,000 pg/ ml. Discard 100 µl of the contents from the last wells used.
      5. Add 100 µl of Sample Diluent in duplicate to the blank wells.
      6. Add 90 µl of Sample Diluent, in duplicate, to the sample wells.
      7. Add 10 µl of each sample, in duplicate, to the designated wells.
      8. Prepare HRP-conjugate.
      9. Add 50 µl of 1:100 diluted HRP-conjugate to all wells including blanks.
      10. Cover with a plate cover and incubate at room temperature (18° to 25°C) for 2 h on a rotator platform.
      11. Remove plate cover and empty wells. Wash Anti-t-PA Coated Plate 3 times. Proceed to the next step.
      12. Pipette 100 µl of TMB Substrate Solution to all wells including blanks.
      13. Incubate the Microwell Strips at room temperature (18° to 25°C) for 15 min on a rotator platform. Avoid direct exposure to intense light. The point at which the substrate reaction should be stopped may be determined by the ELISA reader being used. Many ELISA readers record absorbance only up to 2 Abs Therefore the color development and the substrate reaction must be stopped before positive wells are no longer properly recordable.
      14. Stop the enzyme reaction by quickly pipetting 100 µl of Stop solution into each well including the blanks. It is important that the Stop solution be spread quickly and uniformly throughout the wells to completely inactivate the enzyme. Results must be read immediately after the Stop solution is added or within one h if the Anti-t-PA Coated Plate are stored at 4°C in the dark.
      15. Read absorbance of each microwell on a spectrophotometer at 450 nm as the primary wave length (620 nm as the reference wave length, 610 nm to 650 nm acceptable). Blank the plate reader using the blank wells. Determine the absorbance of the samples and the t-PA standards. Note: incubation without shaking may result in lower than expected Abs values.
      Calculations1. Calculate the average absorbance values for each set of duplicate standards and samples. 2. Create a standard curve by plotting the mean absorbance for each standard concentration on the ordinate against the t-PA concentration on the abscissa. 3. Determine the concentration of circulating t-PA for each sample by finding the mean absorbance value on the ordinate and extending a horizontal line to the standard curve. At the point of intersection, extend a vertical line to the abscissa and read the corresponding t-PA concentration. Calculation of samples with an ABS exceeding the range of the standard curve may result in incorrect/low t-PA levels. These samples should be re-analyzed at higher dilution (1:20 to 1:40) in Sample Diluent to accurately quantitate the t-PA level. Values obtained should be within the expected range of known t-PA controls. 4. A sample standard curve is shown below.
