Measure binding of small molecule drug candidates to target protein in a cellular environment with Alpha CETSA target engagement assays. For use in combination with Pelago Bioscience's CETSA (Cellular Thermal Shift Assay) technology, this kit provides a convenient no-wash assay for detection and quantitation of small molecule binding to EGFR, and can be used in hit identification, hit confirmation, and lead optimization studies for increased confidence and better prediction early in the drug discovery process. Please note that a valid CETSA subscription from Pelago Biosciences is required for use.
