Comparison of two antibodies for immunohistochemical evaluation of epidermal growth factor receptor expression in colorectal carcinomas, adenomas, and normal mucosa
Receptor, Epidermal Growth Factor
The EGFR expression results obtained by immunohistochemistry using both the EGFR PharmaDx kit and the 31G7 clone were comparable. Either antibody may be used for immunohistochemical detection of EGFR in colorectal carcinomas. In addition, manual scoring had an excellent correlation with automated scoring.
