FGFR2 is a receptor for acidic and basic fibroblast growth factors. Defects in FGFR2 are the cause of numerous craniofacial abnormalities such as Crouzon, Jackson-Weiss, and Apert syndromes.The synthetic peptide used to raise the antibody Cat. No. 200106 is selected from a sequence within the N-term region of human FGFR2. For blocking experiments, a 10 to 100 fold molar excess to antibody is recommended.
