Anti-p300 Antibody

Raised in rabbit and affinity-purified by epitope-specific chromatography, this unconjugated polyclonal reagent from Antibodies.com is designed to detect endogenous levels of the p300 (EP300/KAT3B) transcriptional coactivator in human samples. The antibody is supplied as a liquid formulation at 1 mg/mL in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, and is offered in a 50 µL vial. It is of the IgG isotype and was generated against a synthetic peptide derived from the N-terminal region of human p300. Validated applications include Western blotting (WB), immunohistochemistry (IHC) and ELISA, with reactivity confirmed against human tissue and cell-derived samples. For routine handling the product is shipped at 4 °C; on receipt it should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve activity. Together, these specifications make this Antibodies.com anti-p300 antibody a reliable tool for laboratories investigating chromatin-associated gene regulation, histone acetyltransferase activity and p300-dependent signalling pathways.
