Anti-PI3K p85β Antibody

This recombinant rabbit monoclonal antibody targets the PI3K p85α regulatory subunit of phosphatidylinositol 3-kinase, a key scaffold in the PI3K/AKT signaling pathway that controls cell proliferation, survival, and metabolic responses. Manufactured by Antibodies.com as a primary antibody reagent, it is validated for Western blot, immunocytochemistry/immunofluorescence, immunohistochemistry, and flow cytometry applications. Reactivity has been confirmed on human and rat samples, with the unconjugated format allowing direct conjugation or secondary detection flexibility. Each vial contains 100 µl of antibody in TBS buffer (pH 7.4) supplemented with 1% BSA, 40% glycerol, and 0.05% sodium azide preservative; refrigerate upon receipt and avoid repeated freeze-thaw cycles. The p85α isoform (encoded by PIK3R1) is structurally distinct from the related p85β subunit, making this reagent appropriate for researchers investigating isoform-specific phosphoinositide signaling. The product is intended for research use only in laboratory settings such as academic institutions, pharmaceutical discovery, and biomarker studies, and should not be used in diagnostic procedures.
