Anti-CREB (phospho-S133) Antibody

A rabbit polyclonal antibody from Antibodies.com targets the phosphorylated form of CREB at serine 133 (CREB phospho-S133). The unconjugated reagent is raised in rabbit and validated for Western blot (WB), immunohistochemistry (IHC), and immunofluorescence (IF/ICC) applications, with established reactivity against human samples.

The immunogen is a synthetic phosphopeptide derived from human CREB around the phosphorylation site of serine 133. The antibody specifically detects endogenous levels of CREB protein only when phosphorylated at Ser133. It is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, and recognises a target with an apparent molecular weight of approximately 38 kDa. The reagent was affinity-purified from rabbit antiserum using the epitope-specific immunogen, with purity greater than 95% as determined by SDS-PAGE. The product is supported by 2 scientific validation images.
