Bim/Bod is a pro-apoptotic protein belonging to the BH3-only group of Bcl-2 family members, including Bad, Bid, Bik, Hrk and Noxa, which contain a BH3 domain but lack other conserved BH1 or BH2 domains. Bim induces apoptosis by binding to and antagonizing anti-apoptotic members of the Bcl-2 family. Interactions have been observed with Bcl-2, Bcl-xL, Mcl-1, Bcl-w, Bfl-1 and BHRF-1. Bim functions in regulating apoptosis associated with thymocyte negative selection and following growth factor withdrawal, during which Bim expression is elevated. Three major isoforms of Bim are generated by alternative splicing: BimEL, BimL and BimS.

The antibody is stable for at least 1 year from the date of receipt when stored at -20°C to -70°C. Reconstituted antibody can also be aliquotted and stored at 4°C for 1 month or at -20°C to -70°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.

This antibody binds to its immunogen, and did not show any cross reactivity with unrelated antigens in ELISA. Cross reactivity with mouse and rat Bim(GL) has not yet been tested.
