PTC cases were positive for GGT expression, especially at the cell membranes. b HE staining of a PTC case in concordance with A. c Immunohistochemical detection of anti-GT1 antibody. Noncancerous tissue of thyroid tumor cases was negative for GGT expression. d HE staining of a noncancerous tissue in concordance with CBack to article page
