Abstract
A monoclonal antibody, SE-1, which specifically reacted with rat hepatic sinusoidal endothelial cells (HSE), was established with elutriator-separated HSE as immunogen. No crossreactivity was observed with other types of endothelial cells or non-endothelial cells. By immunoelectron microscopy, the antigen recognized by MAb SE-1 was localized to the membrane surface of HSE. Immunoblot analysis revealed that SE-1 recognized a single 45 KD band. Although the SE-1 antigen is not yet characterized, the above evidence strongly suggests that it is related to the specific function of HSE. Therefore, SE-1 may be a useful marker to study the role of HSE in various pathophysiological conditions of the liver.Keywords
