This dataset corresponds to an intact mass spectrometry study focusing on the covalent binding interaction between purified FGFR2 V564F protein and compound LC-F2-1. The purified FGFR2 V564F was adjusted to 28 μM, then incubated with LC-F2-1 at molar ratios of 1:2 or 1:5 for 4 hours at room temperat...
