Product Overview
Clone BEB-16 is a rabbit monoclonal antibody that recognizes phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform (gene PIK3CA) in human, mouse and rat samples and is validated for Western blot, ICC/IF and immunoprecipitation. The predicted molecular weight is 124.3 kDa, and the supplier reports an observed band at about 110 kDa.
PIK3CA encodes p110α, the catalytic subunit of class IA PI3K that converts PI(4,5)P2 into PIP3 downstream of growth factor and insulin receptors. PIP3 recruits AKT and PDK1 to drive growth, survival and metabolism, and activating PIK3CA mutations are among the most frequent in human cancers, making it a major oncology target.
