Bcl-2 Antibody #2876

Applications Reactivity Sensitivity MW (kDa) Source
W H M R Endogenous 28 Rabbit

Applications Key:  W=Western Blotting
Reactivity Key:  H=Human  M=Mouse  R=Rat
Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Bcl-2 Antibody detects endogenous levels of Bcl-2. No cross reactivity was detected with other family members at physiological levels.

Source / Purification

Polyclonal antibodies are prepared by immunizing rabbits with a synthetic peptide (KLH coupled) corresponding to the carboxy-terminus of Bcl-2. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa (human), CTLL-2 (mouse), and PC12 (rat) cells, using Bcl-2 Antibody.

Background

Bcl-2 exerts a survival function in response to a wide range of apoptotic stimuli through inhibition of mitochondrial cytochrome c release (1). It has been implicated in modulating mitochondrial calcium homeostasis and proton flux (2). Several phosphorylation sites have been identified within Bcl-2 including Thr56, Ser70, Thr74 and Ser87 (3). It has been suggested that these phosphorylation sites may be targets of the ASK1/MKK7/JNK1 pathway, and that phosphorylation of Bcl-2 may be a marker for mitotic events (4,5). Mutation of Bcl-2 at Thr56 or Ser87 inhibits its anti-apoptotic activity during glucocorticoid-induced apoptosis of T lymphocytes (6). Interleukin 3 and JNK-induced Bcl-2 phosphorylation at Ser70 may be required for its enhanced antiapoptotic functions (7).
