Anti-BrdU Antibody promotion

To support your cell proliferation experiments, this June, we offer you a free vial of selected Rat Anti-BrdU Antibody, clone BU1/75, products with every vial of Mouse Anti-BrdU Antibody, clone Bu20a*. Our four BrdU antibody double deals are based on like-for-like format matches, and available for a limited time only (offer expires June 30, 2017).

Benefits of the anti-BrdU antibody double deals:

Our anti-BrdU antibody double deals not only enable you to detect BrdU but also other thymidine analogs such as 5′-chloro-2′-deoxyuridine (CldU), 5′-iodo-2′-deoxyuridine (IdU), 5′-ethynyl-2′-deoxyuridine (EdU) and the drug trifluridine when incorporated into DNA (Aten et al. 1992, Liboska et al. 2012, Kitao et al. 2016).

The different cross-reactivities of the two anti-BrdU antibodies to incorporated thymidine analogs and trifluridine are shown in Table 1.

Table 1. Cross-reactivities of the Mouse Anti-BrdU Antibody, clone Bu20a, and Rat Anti-BrdU Antibody, clone BU1/75, to the thymidine analogs BrdU, CldU, EdU, IdU, and the drug trifluridine.

Table adapted from Aten et al. (1992) (BrdU, CldU, and IdU). Cross-reactivity to EdU is based on Liboska et al. (2012) while detection of incorporated trifluridine has been reported by Kitao et al. (2016). Abbreviations: + = reported cross-reactivity, - = no cross-reactivity.
