| Inhibition Assay of BTK Kinase Activity |
Description: | The enzyme reaction mixture of BTK wild type standard HTRF assay contained 1 nM BTK wild type, 1 μM biotin-TK1 peptide, and 30 μM ATP in a buffer. The enzyme reaction were carried out at room temperature for 60 minutes. 5 μl of 0.2 M EDTA were added to quench the reaction and then the inhibitors (5 μl) were added at final concentrations of 2 nM antibody and 62.5 nM XL665. The plates were incubated at room temperature for 60 minutes and then read in the Envision plate reader. The readouts were transformed into inhibition rate % by the equation of (Min Ratio)/(Max-Min)*100%. Hence the IC50 data of test compounds were generated by using four parameters curve fitting. |
