| | Time-Resolved Fret (TR-FRET) Assay |
| Description: | 1) The compound is dissolved in DMSO to prepare a 10 mM solution, and was diluted to 100 micoM with water. When used for IC50 measurement, series dilutions of 10 fold from 100 micoM are used. Kinase activity was determined with time-resolved Fret (TR-FRET) assay (LanthaScreen kinase activity assay, from InVitrogen).2) The assay is performed in a Black 384-well plate (from Corning). The kinase and the compound was incubated for 30 mM at room temperature. ATP (1 mM) and fluorescein-poly GT were added, and the reaction was incubated for 15 mM. Detection agent SA-XL665 (from Cisbio Assay) and TK Ab-Cryptate detection antibody (from InVitrogen) were added to stop the reaction.3) The 384-well plate was sealed and incubated for 1 hour. The fluorescence was then measured at 620 nM (Cryptate) and 665 nM (XL655) wavelength.4) Each concentration of compound was done in triplicate, and vehicle (without compound) and a positive control were used. |
