Protein kinase B (PKB) also known as AKT1 AKT2 and AKT3 encode the RAC alpha, beta, and gamma serine/threonine protein kinases respectively. AKT1 is involved in cellular survival pathways, by inhibiting apoptotic process. It is also able to induce protein synthesis pathways and is therefore a key signaling protein in the cellular pathways that lead to skeletal muscle hypertrophy and general tissue growth. Akt2 is an important signaling molecule in the insulin signaling pathway. AKT3 appears to be predominantly expressed in the brain.

The AlphaLISA SureFire Ultra Multiplex Human and Mouse Phospho-AKT 1/2/3 (Thr308)/Total AKT1 Detection Kit is used to measure phosphorylated AKT 1/2/3 and total levels of AKT1 in cellular lysates in a multiplexing Alpha no-wash assay. No specially engineered cell lines are required. The 615 nm (Eu) signal corresponds to the phosphorylated AKT 1/2/3, and the 545 nm (Tb) signal corresponds to the total AKT1 analysis. This kit has been formulated to provide superior signal:background assay windows and to perform without interference in the presence of extraneous antibodies, making it amenable to the study of therapeutic and blocking antibodies.

• No-wash steps, no separation steps
• Multiplexing assay
• Sensitive detection
• No interference from exogenous antibodies
• Results in less than 3 hours

In this assay, the Alpha 615 Acceptor bead is coated with the CaptSure^™ antibody, which binds the CaptSure-tagged anti-phospho target antibody. The Alpha 545 Acceptor bead is coated with the CaptSure2™ agent, which binds the CaptSure2 tagged anti-total target protein antibody. The Alpha Donor bead binds the biotinylated anti-total target protein antibody.
