Anti-PI3K p85β Antibody

This rabbit polyclonal antibody from Antibodies.com targets the regulatory subunit p85β of class IA phosphoinositide 3-kinase (encoded by PIK3R2) and is validated for Western blot applications across human, mouse, and rat samples. Supplied at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide at approximately pH 7.2, the unconjugated reagent is provided as a 50 µl vial for multiple immunoblotting experiments. PI3K p85β partners with the p110 catalytic subunit to modulate PI3K/AKT signaling, a pathway central to studies of cell proliferation, growth factor responses, and oncogenic transformation. Researchers in cancer biology, insulin signaling, and immunology probe p85β expression to dissect pathway activation and isoform-specific contributions to PI3K signaling.
