AKT is a serine/threonine kinase that plays an important role in multiple biological responses including metabolism, cell survival and growth by phosphorylating many proteins including GSK-3?, caspase-9, BAD, and the Forkhead Transcription Factor. AKT is activated by PI3K, which in turn can interact with FAK and other cytoskeletal-associated proteins, thereby linking activation to the cytoskeleton. AKT/PKB is constitutively active in many types of human cancer, and contributes to tumor progression by promoting angiogenesis and cell invasiveness. AKT is fully activated by phosphorylation of threonine 308 by PDK1 and serine 473 by PDK2. The reactivity of this antibody with AKT2 and AKT3 has not been tested.

Image Legend

Proteins from cell extracts of human Jurkat cells (lane 1), mouse 3T3-L1 cells (lane 2), and rat PC-12 cells (lane 3) were resolved by SDS-PAGE and transferred to PVDF. The membranes were incubated with this AKT monoclonal antibody (clone 9Q7) at a concentration of 1 µg/mL for two hours at room temperature. After washing, the membranes were incubated with a goat F(ab’)2 anti-mouse IgG alkaline phosphatase conjugated antibody (Cat. # AMI4405) at a 1:2000 dilution. Bands were detected with CDP-substrate using the WesternStarTM method (Tropix) and Kodak BioMax film.
