The Alpha SureFire® Ultra™ Multiplex phospho-eIF2α (Ser51) + Total eIF2α assay kit is used to measure both the phosphorylation (on Ser51) and total levels of endogenous eIF2α in cellular lysates. The assay is an ideal system for the screening of modulators of receptor activation (e.g. agonists and antagonists) as well as agents acting intracellularly, such as small molecule inhibitors of signal transduction. The assay will measure eIF2α phosphorylation by either recombinant or endogenous receptors, and can be applied to primary cells.

The Alpha SureFire Ultra Multiplex p-EIF2A + Total EIF2A assay kit is used to measure both phosphorylated and total levels of endogenous EIF2A 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 EIF2A analysis, and the 545 nm (Tb) signal corresponds to the total EIF2A 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.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater ...
Evaluating pharmaceutical compound efficacy and safety in regulating cell behavior can involve the study of multiple signal transduction pathways and measuring more than one cellular target can provide greater confidence of positive compound hits on the cellular target of interest. Protein phosph ...
Cellular kinase signal transduction pathways are involved in the regulation of many important cellular processes such as cell survival, differentiation, and apoptosis. Kinase signaling networks are typically characterized by multiple kinases arranged in cascades containing nodes with feedback loo ...
