BrdU Cell Proliferation Assay KitCatalogue number: X1327K1
|Product Type||Assay Kit|
The BrdU Cell Proliferation Assay Kit is a non-isotopic enzyme immunoassay for the quantification of DNA synthesis and 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. Exalpha Biologicals BrdU Cell Proliferation Assay Kit involves incorporation of BrdU Reagent into cells cultured in microtiter plates using the cell layer as the solid phase. The resultant assay is, 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.

Exalpha’s BrdU Cell Proliferation Assay Kit components are shipped on cold pack. Upon receipt, store kit at -20°C in a non-frost-free freezer. For long term storage, it is recommended that you aliquot and freeze the Prediluted Anti-BrdU Detector Antibody (Component 3) and 2000x Peroxidase Goat anti-Mouse IgG (Component 5) at -20 °C. Thirty (30) minutes prior to the use of each component, thaw component. Remove the Fixative/Denaturing Solution (Component 2) and place at room temperature for at least 4 hours prior to use. The Fixative/Denaturing Solution may contain slight precipitation and its color may vary between clear to light yellow. Return the Prediluted Anti-BrdU Detector Antibody (Component 3) and 2000x Peroxidase Goat anti-Mouse IgG (Component 5) to -20°C immediately after use. All other components may be stored at 4-8°C immediately after use. Special care should be taken to keep the Prediluted Anti-BrdU Detector Antibody (Component 3) and 2000x Peroxidase Goat anti-Mouse IgG (Component 5) cold by pulling out the number of aliquots needed for the test, keeping them on ice, and leaving the remaining aliquots at -20°C.
