| Description: | FGFR2: The in vitro activity of FGFR2 was determined by assaying the phosphorylation level of the substrate in the kinase reaction, by means of an HTRF kinase assay kit. The reaction buffer comprised the following components: 5-fold diluted Enzymatic buffer/kinase 5× (main ingredient: 50 mM HEPES, pH 7.0), 5 mM MgCl2, 1 mM DTT; the human recombinant FGFR2 catalytic structural domain protein (amino acids 400-821) was commercially available from Beijing Sino Biological Inc., diluted with the reaction buffer to a 0.045 ng/μL kinase solution; the substrate reaction solution comprised a biotin labeled tyrosine kinase substrate diluted with the reaction buffer to 800 nM, and 50 μM ATP, and the assay solution comprised an Eu3+ labeled cage-shaped antibody (Cisbio, Catalog number 61T66KLB) diluted with the assay buffer (Cisbio, Catalog number 62SDBRDF) to 0.125 ng/μL, and 50 nM streptavidin labeled XL665. |
