PathHunter® eXpress SYK Activity Assay

PathHunter® CTK Activity cell lines are engineered to express the catalytic domain from CTK of interest fused to the cytokine receptor binding domain (CRBD) of a JAK kinase. The cells co-express an Enzyme Acceptor (EA) tagged SH2 domain and a ProLink™ (PK) tagged Cytokine receptor. The CRBD is designed to bind the CTK catalytic domain to the receptor-PK. Activation of the cytokine receptor-PK induces receptor phosphorylation by the CTK catalytic domain. This leads to SH2-EA recruitment, forcing complementation of the two β-galactosidase enzyme fragments (EA and PK). The resulting functional enzyme hydrolyzes substrate to generate a chemiluminescent signal. These cells have been modified to prevent long term propagation and expansion using a proprietary compound that has no apparent effect on assay performance.

Cells were plated in a 96-well plate and incubated for 24 or 48 hours at 37°C/5% CO2. Cells were then pre-incubated with inhibitor, followed by stimulation with the control agonist . Following agonist stimulation, signal was detected using the PathHunter® detection reagent provided in the kit according to the recommended protocol. For a detailed protocol, please refer to the user manual.
