Our broad portfolio consists of multiplex panels that allow you to choose, within the panel, analytes that best meet your needs. On a separate tab you can choose the premixed cytokine format or a single plex kit.
Cell Signaling Kits & MAPmates™
Choose fixed kits that allow you to explore entire pathways or processes. Or design your own kits by choosing single plex MAPmates™, following the provided guidelines.
The following MAPmates™ should not be plexed together:
-MAPmates™ that require a different assay buffer
-Phospho-specific and total MAPmate™ pairs, e.g. total GSK3β and GSK3β (Ser 9)
-PanTyr and site-specific MAPmates™, e.g. Phospho-EGF Receptor and phospho-STAT1 (Tyr701)
-More than 1 phospho-MAPmate™ for a single target (Akt, STAT3)
-GAPDH and β-Tubulin cannot be plexed with kits or MAPmates™ containing panTyr

Supplied with a positive control consisting of phosphoproteins purified from rabbit muscle lysate by Fe3+-IDA affinity chromatography.
Background
Protein phosphorylation is the principal indicator of the activation of signaling pathways. The binding of a growth factor to its specific receptor catalyzes a complex cascade of intracellular signaling events, characterized by altering the phosphorylation of tyrosine, serine, or threonine residues of target proteins. The phosphorylation state is tightly regulated by the actions of protein kinases, which transfer a phosphate group from donor substrates such as ATP or GTP to serine, threonine, or tyrosine residues, and protein phosphatases, which dephosphorylate phosphorylated proteins, thereby restoring the particular phosphorylation system to its basal stage. Most kinases are either serine/threonine-specific or tyrosine-specific, while some kinases can phosphorylate all 3 types of hydroxy-bearing amino acids. Radioactive kinase assays utilizing 32P-γ-ATP as the donor substrate have been frequently employed to assess kinase activity, since the method is sensitive, convenient, and easily quantified. Recently, however, the generation of phosphoprotein-specific antibodies has advanced the development of non-radioactive kinase activity detection methods to comparable sensitivity as radioactive methods. Antibodies specific for phosphorylated epitopes recognize the phosphorylated amino acid in the context of the surrounding amino acid sequence. Recognition, therefore, depends on 2 criteria: 1) phosphorylation and 2) the surrounding amino acid motif. If one of the two criteria is not fulfilled, the antibody will not detect the phosphorylation site. Since the surrounding amino acid sequence varies between phosphorylation sites, certain proteins, though phosphorylated, may not be detected by a given antibody.
