CST, 66915W2, Phospho-Bcl-2 (Ser70) (5H2) Rabbit Monoclonal Antibody (SignalFlex™ Pacific Blue™ Conjugate)

Monoclonal Antibody for studying Bcl-2 (Ser70) phosphate. Highly specific and rigorously validated in-house, Phospho-Bcl-2 (Ser70) (5H2) Rabbit Monoclonal Antibody (SignalFlex^™ Pacific Blue^™ Conjugate) (CST #66915) is ready to ship. Product Usage Information SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology ® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays. Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate. Storage Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze. Specificity / Sensitivity Phospho-Bcl-2 (Ser70) (5H2) Rabbit mAb (SignalFlex™ Pacific Blue™ Conjugate) detects endogenous levels of Bcl-2 only when phosphorylated at serine 70. The antibody does not cross-react with nonphosphorylated Bcl-2 at endogenous levels or with other Bcl-2 family members. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding serine 70 of human Bcl-2. 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 anti-apoptotic functions (7).
