          PIK3CA Antibody (PA5-99395) in ICC/IF

          Immunofluorescent analysis of PIK3CA in HeLa cells. Samples were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100, blocked with 10% serum (45 min at 25°C), incubated with mouse anti-beta tubulin and PIK3CA polyclonal antibody (Product # PA5-99395) using a dilution of 1:200 (1 hr, 37°C), and followed by goat anti-rabbit IgG Alexa Fluor 594 (red) and goat anti-mouse IgG Alexa Fluor 488 (green). {{ $ctrl.currentElement.advancedVerification.fullName }} validation info.

          Product Specific Information

          Antibody detects endogenous levels of total PI3 kinase P110 alpha.

          Target Information

          Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. This gene has been found to be oncogenic and has been implicated in cervical cancers.
