ASK1/2 Biochemical Assays (IMAP Technology): IMAP technology provides a homogeneous assay applicable to a wide variety of kinases, phosphatases, and phosphodiesterases without regard for substrate peptide sequence. The assay is a simple mix-and-read procedure allowing accurate determination of enzyme activity. Based on the specific, high-affinity interaction of phospho groups with trivalent metal-containing nanoparticles (beads), IMAP is a generic, non-antibody-based platform to assess kinase, phosphatase, and phosphodiesterase activity. An enzyme reaction is performed using fluorescently labeled substrate. Addition of the IMAP Binding System stops the enzyme reaction and initiates binding of the beads to phosphorylated substrates. Binding of the substrate to the beads, which correlates to enzyme activity, can be detected using either FP or TR-FRET as a readout.
