The antiserum was produced against synthesized phospho-peptide derived from human PI 3-kinase p85beta around the phosphorylation site of Tyr464.
Purification
The antibody was purified from rabbit antiserum by affinity-chromatography using phospho peptide. The antibody against non-phospho peptide was removed by chromatography using corresponding non-phospho peptide.
Specificity
PI 3-kinase p85beta (Phospho-Tyr464) antibody detects endogenous levels of PI 3-kinase p85beta only when phosphorylated at Tyr464.
