We have also developed the Click-i T® Ed U Microplate Assay that employs the nucleoside analog Ed U (5-ethynyl-2’-deoxyuridine) and a detection method that is not antibody-based, so it does not require DNA denaturation.The advantage of these incorporation assays is that they are direct measures of proliferation.When a scientist injects Brd U into the bloodstream of a test animal, the chemical becomes available to all cells – most importantly, those which are proliferating.
Brd U is commonly used in the detection of proliferating cells in living tissues.
(See a list of the products featured in this article.) Cell proliferation assays provide a critical piece of the puzzle when evaluating cell health, genotoxicity, and the efficacy of anti-cancer drugs.
Proliferation, however, is rarely assayed in isolation; other cell function probes are often used in concert with proliferation assays to provide a more informative picture of the state of the cell.
Cell proliferation can be measured with the thymidine analog Brd U (5-bromo-2’-deoxyuridine) following its incorporation into newly synthesized DNA and its subsequent detection with an anti-Brd U antibody.
Bromodeoxyuridine, variously abbreviated as Brd U, Bud R, and Brd Urd, is a halogenated thymidine analog that is permanently integrated into the DNA of dividing cells during DNA synthesis in S phase. (2008) Identification of Newborn Cells by Brd U Labeling and Immunocytochemistry In Vivo.
Since the two chemicals are analogous, some spots of the genetic code that call for Thymidine will instead receive Brd U.
