Assay Method Information

Assay Name:  KiNativ assay
Description:  Sample preparation: A375 cells from ATCC are lysed by sonication in commercially available lysis buffer, cleared by centrifugation, and the resulting supernatant gel filtered into a commercially available kinase reaction buffer containing 20 mM MnCl2. Final protein concentration of lysates are 10 mg/mL. 5 ul of each test compound is added from 100 uM, 10 uM, 1 uM, or 0.1 uM stock solutions in DMSO to 500 uL of lysate in duplicate for final concentrations of 1 uM, 0.1 uM, 0.01 uM, and 0.001 uM. 5 ul, of DMSO is added to 500 ul of lysate in quadruplicate for controls. After 15 minute incubation, desthiobiotin-ATP acylphosphate probe is added to each sample to a final concentration of 5 uM and incubated with the samples for 10 minutes. Following the probe reaction, samples are prepared for targeted mass spectrum analysis using ActivX standard protocol.
