title: Isolation and characterization of low molecular weight antibodies for Treponema pallidum.
abstract: A low molecular weight antibody which coated Treponema pallidum without producing any apparent reaction was isolated from human syphilitic serum. Its electrophoretic mobility was that of IgG immunoglobulins, and molecular weight was between 115,000 and 120,000.
