title: Production of monospecific antibodies to a low-abundance hepatic membrane protein using nitrocellulose immobilized protein as antigen.
abstract: Membrane proteins from primary cultures of rat hepatocytes were separated by two-dimensional polyacrylamide gel electrophoresis. The proteins were transferred to nitrocellulose paper which was then dissolved in dimethyl sulfoxide and this mixture was used as a primary immunogen in rabbits. Subsequent immunizations were performed using nonsolubilized protein immobilized on nitrocellulose paper. A monospecific polyclonal antibody was generated against a specific mitochondrial membrane protein (MP-73) for which de novo synthesis appeared to be induced by amino acid starvation of the hepatocytes. A minimum of 15-20 micrograms of protein antigen was required to elicit significant antibody production. Serum antibody titer was sufficient to allow detection of MP-73 at a serum dilution of 1:2000.
