Anti-PI3K p85β Antibody

The PI3K p85β regulatory subunit serves as one of the adaptor proteins that modulates class IA phosphoinositide 3-kinase signaling, a pathway central to studies of cell growth, survival, insulin response, and oncogenic transformation. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against the p85β isoform and is supplied as 100 µl of antibody at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2. Intended for research use only, the reagent should be stored refrigerated, with aliquots prepared for repeated western blot experiments. Validated for western blot application, the antibody cross-reacts with human, mouse, and rat samples, supporting comparative signaling studies across these species. Provided as a liquid in a single-use vial, the polyclonal format offers recognition of multiple epitopes on p85β, which is helpful when working with post-translational modifications or isoform-specific signaling complexes. Researchers commonly deploy this reagent to probe PI3K pathway activation status in cell lysates and tissue extracts.
