Immunohistochemical Localization in Rat Gastrointestinal Tract of a Sialomucin Species Recognized by HCM31, a New Anti-Mucin Monoclonal Antibody

Abstract

it has been recognized that distinct mucus secreting cells of the gastrointestinal tract express specific type of tnucins. We have recently demonstrated that a kind of sialomucin specifically stained with a monoclonal antibody (mAb) HCl\/I31 is temporarily and specifically expressed in the mucous cells regenerated from acetic acid-induced gastric damage in rats. The aim of this study was to iinmunohistochemically characterize the distribution of the specific type of sialomucins recog-
