| | ASK1/2 Biochemical Assays (AlphaScreen Technology) |
| Description: | ASK1 and ASK2 biochemical activities were also quantified using AlphaScreen technology which measures the degree of phosphorylation of a protein substrate (MKK7). AlphaScreen technology is based on the binding of a substrate to two types of beads, acceptor and donor. Binding to one bead is through the tag of the substrate protein. Binding of the second bead is through phosphospecific binding of antibody to the phosphosite of the substrate. This forms a sandwich, with the acceptor and donor beads in close proximity. When the donor beads are excited by light in the 680 nm range, a singlet oxygen is released and causes emission of light from the acceptor in the 620 nm range which can be detected using a suitable plate reader. |
