Carcinoembryonic antigen present in human eccrine sweat

N S Penneys et al. J Am Acad Dermatol. 1981 Apr.

Abstract

Carcinoembryonic antigen is detectable by standard unlabeled peroxidase-antiperoxidase technics in eccrine and apocrine secretory and ductal cells. Carcinoembryonic antigen is also present in the cuticle which lines the duct. In eccrine sweat, carcinoembryonic antigen activities were at least thirty times that in serum, using a radioimmunoassay. Carcinoembryonic antigen may form part of the Schiff-positive cuticle and function in the normal homeostasis of eccrine and apocrine glands.
