Anti-PIK3R2 Antibody

Phosphoinositide 3-kinase regulatory subunit 2 (PIK3R2), also known as p85β, acts as the regulatory adaptor of class IA PI3K, stabilizing and modulating the p110 catalytic subunit within the PI3K/AKT signaling cascade. This unconjugated rabbit polyclonal antibody from Antibodies.com binds PIK3R2 and is validated for Western blot and immunohistochemistry applications on human and rat tissue samples, including formalin-fixed paraffin-embedded sections. Because the reagent is polyclonal, it recognizes multiple epitopes across the target, supporting robust detection in signaling studies of insulin receptor signaling, growth factor responses, and downstream AKT phosphorylation events relevant to cancer, metabolic, and cell biology research. Supplied as 100 µl, the unconjugated format lets researchers pair the antibody with their preferred HRP, biotin, or fluorescent secondary reagents, or use it directly in immunoprecipitation workflows where a clean primary is required. Short-term storage should be refrigerated; for longer projects, aliquot the antibody and freeze it, then protect from light and limit freeze-thaw cycles to preserve binding activity. The product is intended for research use only and is not validated for diagnostic or therapeutic applications.
