We have produced a new protein-specific monoclonal antibody (MAb) to rat liver beta 1 --> 4 galactosyltransferase. This MAb, GTL2, was selected as the most reactive IgG to a periodate-treated antigen. Antigen and protein specificities of GTL2 were verified by immunoblotting of a non-glycosylated recombinant protein of human galactosyltransferase and enzymatically deglycosylated rat galactosyltransferase. Using GTL2, an immunohistochemical study was done in rat liver, epididymis, and salivary glands. Intense staining was observed in Golgi areas of epididymal duct epithelial cells, and submandibular and sublingual acinar cells. Hepatocytes showed weaker staining. Immunoelectron microscopic observation revealed that the staining was exclusively localized in trans-Golgi membranes of these cells.
