title: Monoclonal antibody to human plasma gelsolin.
abstract: Human plasma gelsolin was purified by column chromatography. The method yielded a protein of high purity and activity. Using this protein, we produced monoclonal antibody (Mab H6B11) against human plasma gelsolin by somatic cell fusion. This monoclonal antibody reacted in a dose-dependent manner with gelsolin derived from human plasma and platelets and neutralized depolymerizing activity to F-actin. It differed from the commercially available substance (Mab G4896; Sigma) in that the time required for the reaction between the antigen and antibody in the enzyme-linked immunosorbent assay could be shortened by one-third. The antibody was judged to be useful in assays for elucidating the physiological role of plasma gelsolin.
