title: A monoclonal antibody directed against an organ-specific liver cell membrane antigen in rabbits.
abstract: We generated monoclonal antibodies after immunization of mice with rabbit liver-specific protein (LSP) preparations. One of these antibodies (2D3) showed an organ-specific and species-specific binding pattern as determined by immunohistological and ELISA techniques. Immunoelectron microscopy studies demonstrated that this antibody is bound exclusively to the liver cell membrane except in the region of the bile canaliculi. We further describe a simple ELISA technique for the detection of anti-LSP antibodies. Our study clearly demonstrates the presence of at least 1 organ-specific liver cell membrane antigen in rabbit LSP and shows antigenic differences between areas of the plasma membrane of hepatocytes.
