Detection of Human PI 3-Kinase p85 beta by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human PI 3-Kinase p85 beta Monoclonal Antibody (Catalog # MAB6777) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PI 3-Kinase p85 beta at approximately 100 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

PI 3‑Kinase p85 beta in K562 Human Cell Line. PI 3-Kinase p85 beta was detected in immersion fixed K562 human chronic myelogenous leukemia cell line using Mouse Anti-Human PI 3-Kinase p85 beta Monoclonal Antibody (Catalog # MAB6777) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: PI 3-Kinase p85 beta

Phosphoinositide 3-kinase p85 beta subunit (PI 3-Kinase p85 beta ), also called regulatory subunit 2 (PIK3-R2) is an 85 kDa, 728 amino acid (aa) regulatory subunit of the PI3K complex. It shares ubiquitous expression and overlapping function with the p85 alpha subunit, but the two are differentially phosphorylated and may have different effects on apoptosis. Within aa 516-642, human p85 beta shares 97%, 96% and 68% aa identity with mouse and rat p85 beta and human p85 alpha, respectively. Full-length human p85 alpha and p85 beta share 59% aa identity.
