Monoclonal Antibody to Bcl-2 (Clone: BC1)

Bcl-2 (B-cell lymphoma 2), is a member of Bcl-2 family of regulator proteins. These proteins contain a hydrophobic cleft that binds to BH3-only proteins and to the pro-apoptotic Bcl-2 family members Bad, Bak, and Bax to inhibit apoptosis. In the absence of this binding, the proapoptotic Bcl-2 members are recruited to the OMM (Outer Mitochondrial Membrane) at which they oligomerize and cause OMM permeabilization, releasing proapoptotic effectors such as SMAC or cytochrome-c. Bcl-2 also neutralize a group of 'sensor' proteins (such as BIM), which are triggered by cytotoxic stimuli such as chemotherapy. BCL-2 proteins therefore have a central role as guardians against apoptosis, helping cancer cells to evade cell death.
