      Intended useThe BrdU Proliferation Assay (Cat. No. HTS01) is a non-isotopic immunoassay for the quantitation of bromodeoxyuridine incorporation into newly synthesized DNA of actively proliferating cells.
      BackgroundEvaluation of cell cycle progression is essential for investigations in many scientific fields. Measurement of [3H] thymidine incorporation as cells enter S phase has long been the traditional method for the detection of cell proliferation. Subsequent quantification of [3H] thymidine is performed by scintillation counting or autoradiography. This technology is slow, labor intensive and has several limitations including the handling and disposal of radioisotopes and the necessity of expensive equipment. A well-established alternative to [3H] thymidine uptake has been demonstrated by numerous investigators. In these methods bromodeoxyuridine (BrdU), a thymidine analog, replaces [3H] thymidine. BrdU is incorporated into newly synthesized DNA strands of actively proliferating cells. Following partial denaturation of double stranded DNA, BrdU is detected immunochemically allowing the assessment of the population of cells, which are actively synthesizing DNA. This BrdU Proliferation Assay (Cat. No. HTS01) involves incorporation of BrdU into cells cultured in microtiter plates and BrdU immunolabeling using the cell layer as the solid phase. The resultant assay is sensitive, rapid, easy to perform and applicable to high sample throughput. In addition to evaluation of cell proliferation, information such as cell number, morphology and analysis of cellular antigens can be obtained from a single culture.
      Principles of the assayThe BrdU Proliferation Assay (Cat. No. HTS01) involves incorporation of BrdU into cells cultured in microtiter plates and BrdU immunolabeling using the cell layer as the solid phase. During the final 2 to 24 h of culture BrdU is added to wells of the microtiter plate. BrdU will be incorporated into the DNA of dividing cells. To enable antibody binding to the incorporated BrdU, cells must be fixed, permeabilized and the DNA denatured. This is all done in one step by treatment with Fixative/Denaturing Solution. Detector anti-BrdU monoclonal antibody is pipetted into the wells and allowed to incubate for one hour, during which time it binds to any incorporated BrdU. Unbound antibody is washed away and horseradish peroxidase-conjugated goat anti-mouse is added, which binds to the detector antibody.
      The horseradish peroxidase catalyzes the conversion of the fluorogenic substrate to a blue fluorescent product the intensity of which is proportional to the amount of incorporated BrdU in the cells. The blue fluorescent product is quantified using a fluorometer.
      Materials providedThe BrdU Proliferation Assay is provided in either a 200 test kit or a 1000 test kit.

      Reagent preparationBefore first use: 1. Remove the Fixative/Denaturing Solution and place at room temperature for at least 4 h prior to use. Precipitates that may occur while cold should go back into solution. 2. Reconstitute the Peroxidase Goat Anti-Mouse IgG with the appropriate volume of PBS. • For the 200 test kit, reconstitute Peroxidase Goat Anti-Mouse IgG in 125 µl of PBS • For the 1000 test kit, reconstitute Peroxidase Goat Anti-Mouse IgG in 250 µl of PBS Allow solution to stand at room temperature for 10 min. (or until solution is clear). Divide into small aliquots; aliquots not to be used that same day should be stored at -20°C in a non-frostfree freezer. Once the kit components have been thawed for use: • The BrdU label and 100X Anti-BrdU Antibody should be divided into small aliquots and stored at -20°C in a non-frostfree freezer with the Peroxidase Goat Anti-Mouse IgG; avoid multiple freeze/thaw cycles. • All the other kit components (Substrate, Peroxide Solution, Antibody Diluent, Conjugate Diluent, 20X Plate Wash Concentrate, Fixative/Denaturing Solution, Stop Solution) should be stored at 4°C.
      Detailed protocol1. The BrdU Proliferation Assay is provided with all reagents necessary to run 200 (or 1000) tests or microtiter plate wells. Replicate samples should be assayed due to variation in biological responses at the cellular level. Disposable pipette tips and reagent troughs should be used for all transfers to avoid cross-contamination of reagents or samples.
      2. Seed 100 µl of cells at 104 to 106 cells/ml into a 96 well culture dish. If adherent cells are being used, allow cells to attach prior to treatment with test substance (i.e. proliferation inducer or inhibitor). Two types of controls should also be set up to insure validity of the experiment.
      I. Blank: Add only tissue culture media (no cells).
      II. Background: Cells are present in the wells but do not add the BrdU Label. Follow protocol as usual from step 6.
      3. Prepare a working stock of BrdU by diluting the BrdU Label 1:2000 into fresh tissue culture media (for example, add 2 µl of BrdU Label to 4 ml fresh tissue culture media).
      4. Pipette 20 µl of this working stock to each well to be labeled.
      5. Allow BrdU to incubate with cells for 2-24 h in the tissue culture incubator (Figure 1). If non-adherent cells are being used, centrifuge 96 well dish for 10 min at 1000 rpm.
      6. Remove contents of wells by inverting over sink and blot gently on paper towels.
      7. Add 200 µl of the Fixative/Denaturing Solution to each well.
      8. Incubate for 30 min at room temperature.
      9. Remove contents of wells by inverting over sink and tapping on paper towels. Plates may be stored after this step at 4°C for 1 week.
      10. Dilute the 100X Anti-BrdU Antibody 1:100 in the Antibody Dilution Buffer (i.e. 120 µl to 12 ml of Antibody Diluent). Pipette 100 µl of this solution to each well and incubate for 1 h at room temperature.
      11. Prepare a working solution (1X) of Wash Buffer by adding 25 ml of the 20X concentrated solution (provided), to 475 ml of deionized water. Mix well.
      12. Wash wells 3 times with automatic plate washer or by hand with 1X Wash Buffer making sure each well is filled completely. Blot the plate gently on paper towels.
      13. Prepare the conjugate by diluting the reconstituted Peroxidase Goat Anti-Mouse IgG HRP Conjugate in the Conjugate Diluent and syringe filter through 0.2 micron filter. NOTE: Dilution of conjugate is lot specific. Refer to vial label for lot specific dilution.
      14. Pipette 100 µl of this solution into each well and incubate for 30 min at room temperature.
      15. Prepare a Fluorogenic Substrate Working Stock Solution by mixing 9 parts Fluorogenic Substrate to 1 part Fluorogenic Peroxide Solution. The Working Stock Solution is stable for 24 h at room temperature and no protection from light is required. Prepare only the amount of Working Stock Solution that will be used within 24 h.
      16. At the end of the 30 min incubation (step 14), wash wells 3 times with automatic plate washer or by hand with 1X Wash Buffer making sure each well is filled completely.
      17. FLOOD ENTIRE PLATE WITH dH2O. Remove contents of wells by inverting over sink and tapping on paper towels.
      18. Add 100 µl of Fluorogenic Substrate Working Stock Solution (prepared in step 15.) to each well and incubate at room temperature for 30 min.
      19. Add 100 µl of Stop Solution to each well in the same order as the previously added Substrate Solution.
      20. Measure plate on a Fluorometer capable of measuring excitation ~325 nm and emission ~420 nm. (The assay was validated with a BMG FLUOstar Fluorometer with a 320 nm excitation and a 460 nm emission filter). Wavelengths between 315 and 340 nm for excitation and 370 and 470 nm for emission can be used for detection. Wells must be read within 30 min of adding the Stop Solution.
      Assay characteristics and examplesThe data can be expressed as the relative signal (RFU) after subtraction of the relative signal of the appropriate buffer controls (Figure 2 and 3). The data may also be expressed as a ratio of signal obtained from a labeled sample (+BrdU) to an unlabeled sample (-BrdU) after subtraction of the appropriate endogeneous fluorescence or buffer controls (Figure 3).

Unbound antibody is washed away and horseradish peroxidase-conjugated goat anti-mouse is added, which binds to the detector antibody. In the presence of hydrogen peroxide, the HRP catalyzes the conversion of the substrate to produce a highly fluorescent product the signal of which is proportional to the amount of incorporated BrdU in the cells.


      Figure 3: Signal/Noise Ratio and Signal at 320 Excitation/405 Emission vs. 320 Excitation/

      At 405 nm emission, the signal is increased. At 460 nm emission, the ratio of BrdU labeled to the no BrdU control is generally higher. The cells were label with BrdU for 24 h, the no cell controls were not subtracted from the data.


      Figure 4: Sensitivity

      With a 24 h BrdU labeling 600 plated cells (~1,800 growing cells per well) can easily be distinguished from background.
