Bcl-2 Antibody (Human Specific) #2872
| Applications | Reactivity | Sensitivity | MW (kDa) | Source |
|---|---|---|---|---|
| W | H | Endogenous | 28 | Rabbit |
Applications Key:
W=Western Blotting
Reactivity Key:
H=Human
Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Bcl-2 antibody (Human Specific) detects endogenous levels of total Bcl-2 protein. The antibody does not cross-react with other Bcl-2 family members.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues surrounding Gly41 of human Bcl-2, a region not conserved in mouse or rat. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from Jurkat and THP-1 cells using Bcl-2 Antibody (Human Specific).
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).
