Revvity, MPSU-PTAKT-N500, AlphaLISA Multiplex Human and Mouse Phospho-AKT1/2/3 (Thr450 & Total) Detection Kit, 500 Assay Points

Overview
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 (Thr450)/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.

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.
How it works
Multiplex SureFire Ultra assay principle
The Multiplex SureFire Ultra assay simultaneously measures phospho and total protein at specific levels. It utilizes three antibodies that recognize the phospho epitope and two distal epitopes on the target protein. The assay requires three bead types: two distinct acceptor beads and one donor bead.

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 antibody, which binds the CaptSure2-tagged anti-total target protein antibody.
The Alpha donor bead binds the biotinylated anti-total target protein antibody.

When the phosphorylated protein is present, the three antibodies bring the donor and acceptor beads close together, allowing singlet oxygen to transfer energy and excite both acceptor beads. This generates a luminescent Alpha signal at 615nm and 545nm. The 615nm (Eu) signal is directly proportional to the amount of phosphorylated protein, while the 545nm (Tb) signal corresponds to the total protein levels.

Multiplex SureFire Ultra two-plate assay protocol
The two-plate protocol involves culturing and treating the cells in a 96-well plate before lysis, then transferring lysates into a 384-well Optiplate™ plate before the addition of Multiplex SureFire Ultra detection reagents. This protocol enables the cells viability and confluence to be monitored. In addition, lysates from a single well can be used to measure different targets.

Multiplex SureFire Ultra one-plate assay protocol
Detection of phosphorylated/total target proteins with Multiplex SureFire Ultra reagents can be performed in a single plate used for culturing, treatment, and lysis. No washing steps are required. This HTS designed protocol enables miniaturization while maintaining robust AlphaLISA SureFire Ultra quality. Application-Cell Signaling
