Anti-PI 3-kinase p85α / γ Antibody

Distributed through Antibodies.com, this 50 µL aliquot of affinity-purified rabbit polyclonal antiserum is raised against a synthesized peptide derived from the human PI 3-kinase p85 / p55 sequence spanning the non-phosphorylation site at tyrosine 458/199, enabling selective detection of endogenous PI 3-kinase p85α / γ protein. Supplied unconjugated at 1 mg/mL in a liquid formulation of PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide, the reagent is shipped at 4 °C and, upon arrival, should be aliquoted and stored at −20 °C with care taken to avoid repeated freeze/thaw cycles. The antibody has been validated for ELISA, Western blot (WB), immunocytochemistry/immunofluorescence (ICC/IF), and immunohistochemistry (IHC), and cross-reactivity has been confirmed against human, mouse, rat, and monkey samples, which makes it well suited to comparative signaling studies of the PI3K regulatory subunits in cell lysates and tissue sections. Purification is performed by affinity chromatography against the epitope-specific immunogen, supporting low-background performance across the recommended applications. Provided for research use only and not intended for diagnostic or therapeutic purposes, this polyclonal reagent offers a versatile option for laboratories investigating phosphoinositide 3-kinase pathway components in oncology, immunology, and metabolic disease research.
