Abstract:
:A DBA/1 B10.D2-specific monoclonal antibody (CY34) is described which defines a new murine B lymphocyte differentiation antigen designated Lyb-8.2. The ontogeny, strain distribution, and cell-surface density of the antigen were studied by radioimmunoassay and by fluorescence-activated cell sorter (FACS) analysis. Lyb-8.2 appears to be expressed on pre-B cells and on all mature B lymphocytes. Lyb-8.2 molecules immunoprecipitated from surface labeled B10.D2 spleen cells migrated in polyacrylamide gels with an apparent mol. wt. of 95,000-105,000 daltons and were bound by lentil lectin. The expression of Lyb-8.2 is controlled by a locus on chromosome 7 that is closely linked to Gpi-1 and RP-2. Added Lyb-8.2-specific antibody did not measurably impair B lymphocyte function in several in vitro systems studied.
