Product Overview
Clone EIC-16 is a rabbit monoclonal antibody that recognizes phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (gene PIK3CB) in human samples and is validated for Western blot, immunoprecipitation and flow cytometry. The predicted molecular weight is 122.8 kDa, and the supplier reports an observed band at about 110 kDa.
PIK3CB encodes p110β, a class IA PI3K catalytic subunit that produces PIP3 and activates AKT signaling. Unlike p110α, it can be activated by G protein-coupled receptors as well as tyrosine kinases, and it is studied in platelet function, insulin signaling and PTEN-deficient tumors.

Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human PI3 Kinase p110 beta.
Reactivity Notes
The supplier lists reactivity with human. UniProt places phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Expressed ubiquitously. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
