Intended useThe Calbiochem® BrdU Cell Proliferation Assay is a non-isotopic immunoassay for the quantitation of bromodeoxyuridine incorporation into newly synthesized DNA of actively proliferating cells.
BackgroundA non-isotopic enzyme immunoassay for the quantification of cell proliferation. Evaluation 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. The Calbiochem® BrdU Cell Proliferation Assay involves incorporation of BrdU into cells cultured in 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 Calbiochem® BrdU Cell Proliferation Assay involves incorporation of BrdU into cells cultured in 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 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 1 h, 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 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 incorporated BrdU in the cells. The colored reaction product is quantified using a spectrophotometer.

Detailed protocol1. The BrdU Cell Proliferation Assay is provided with all reagents necessary to run 200 (or 1000) tests or microwell 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 1-2 X 105 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.
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.
6. If non-adherent cells are being used, centrifuge 96 well dish for 10 min at 1000 rpm.
7. Remove contents of wells by inverting over sink and blot gently on paper towels.
8. Add 200 µl of the Fixative/Denaturing Solution to each well.
9. Incubate for 30 min at room temperature.
10. 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.
11. 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.
12. 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.
13. 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.
14. Prepare the conjugate by diluting the reconstituted (in 1X PBS) 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.
15. Pipette 100 µl of this solution into each well and incubate for 30 min at room temperature.
16. 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 Substrate Solution to each well and incubate IN THE DARK at room temperature for 15 min.
19. Add 100 µl of Stop Solution to each well in the same order as the previously added Substrate Solution.
20. Measure absorbance in each well using a spectrophotometric plate reader at dual wavelengths of 450-540 nm (or 450-595). Wells must be read within 30 min of adding the Stop Solution.
Example dataThe promyelocytic cell line HL-60 can be induced to differentiate with phorbol ester (PMA) or retinoic acid (RA). Differentiated HL-60 cells lose the ability to proliferate in culture. To demonstrate the utility of the BrdU Cell Proliferation Assay in measuring the dose response of the two drugs 2 X 10⁴ cells/well (2 X 10⁵ cells/ml) were incubated with various concentrations of PMA or RA for 24 h (37°C, 7% CO₂). BrdU Label was added and the cells incubated for an additional 24 h. Incorporated BrdU was detected by the BrdU Cell Proliferation Assay. The concentrations of these two drugs where HL-60 exits the cell cycle concomitant with the onset of myeloid maturation was found by the BrdU Cell Proliferation Assay. In another series of experiments, the BrdU Cell Proliferation Assay detected the dose of thymidine and phorbol ester that caused cell cycle arrest in both adherent cells line and non-adherent cell lines. A kinetic/sensitivity study was performed using the PMA treated HL-60 system. Various concentrations of HL-60 cells were growth arrested by treatment with 20 ng/ml PMA. After 24 h the HL-60 cells were incubated with BrdU Label for 24, 18, 4 or 2 h and incorporated BrdU was detected by the BrdU Cell Proliferation Assay. There was a direct relationship between the signal and number of proliferating cells at all labeling times. With one exception, the signals of proliferating cells were significantly higher than the background control (-BrdU) and blank control (no cells). The 2-h BrdU labeling at 160 cells/well was not significantly higher than the blank control. Similar results were demonstrated with the Daudi cell line and the HT1080 cell line. The sensitivity of the BrdU Cell Proliferation Assay (Cat. No. QIA58) was compared to a BrdU Proliferation Assay of a competitor using two cell lines. The BrdU Cell Proliferation Assay was more sensitive (signal of proliferating cells over no cells) at all BrdU labeling times. In many different systems both the 24 h and 2 h BrdU labeling times detected proliferating cells.
