TSSK2 Human CAMK Kinase Enzymatic Radiometric LeadHunter Assay [10 μM ATP] - TW

Procedure Summary:

Human recombinant protein kinase TSSK2 expressed in insect Sf21 cells is used. Test compound is preincubated with 0.33 U/ml enzyme‡ in modified MOPS buffer pH 7.2 for 15 minutes at 37°C. The reaction is initiated by addition of 10 μM CHKtide, 10 μM ATP containing 0.25 μCi[γ32P]ATP for another 30 minute incubation period and terminated by further addition of 3% H3PO4. An aliquot is removed and counted to determine the amount of [32P]CHKtide. Compounds are screened at 10 μM.
