title: Monoclonal hybridoma antibodies to human amyloid related protein SAA.
abstract: Problems concerning isolation and characterization of the amyloid related serum protein SAA in a pure form prompted us to make monoclonal antibodies to the protein. Protein SAA isolated by gel filtration under dissociating conditions was used for immunization of BALB/c mice, and spleen cells from a mouse producing high titred antiserum to SAA were fused with cells from the mouse plasmacytoma line P3U1. Antibody specificity to various preparations of protein SAA was tested using an indirect enzyme-linked immunosorbent assay. Monoclonal antibodies with specificity for SAA were obtained in addition to antibodies which reacted with both SAA and the related amyloid protein AA. Antibodies specific for one of the apoC proteins of the lipoprotein fraction were also produced showing that the SAA preparation used for immunization was contaminated with apoC proteins.
