  • Title: Production and characterization of monoclonal antibodies to bovine immunoglobulin G2.
    Author: Srikumaran S, Guidry AJ, Goldsby RA.
    Journal: Am J Vet Res; 1982 Jan; 43(1):21-5. PubMed ID: 7091814.
    Abstract:
    Spleen cells from Balb/cJ mice inoculated with bovine immunoglobulin (Ig)G were hybridized with hypoxanthine aminopterin thymidine-sensitive nonsecreting cell line SP-2/0, and the hybrid cell culture fluid was tested for specificity. Hybrid cells secreting monoclonal antibodies to bovine IgG were isolated and recloned. The monoclonal antibody DAS 2 was specific for bovine IgG2 by an indirect solid-phase radioimmunoassay. This clone was adapted for growth as antibody-secreting neoplasms in Balb/cJ mice, the sera from which contained high titers (1:128,000) of anti-bovine IgG2 antibodies. Antibody specific to bovine IgG2 was isolated by affinity chromatography. This antibody was shown by Ouchterlony analysis to be mouse IgG1 with the kappa light chain. On isoelectric focusing, this antibody gave a pattern that was consistent with monoclonality.
