Product Overview
Clone 30P53 is a rabbit monoclonal antibody that recognizes phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (gene PIK3CB) in human, mouse and rat samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 122.8 kDa, and the supplier reports an observed band at about 123 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.

Samples with confirmed staining (IHC): human colon tissue, human colon cancer tissue, mouse brain tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human PI3 Kinase p110 beta.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. 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.
