title: Identity of the V kappa 10-Ars-A gene segments of the A/J and BALB/c strains.
abstract: To characterize the light chain gene segments involved in the murine immune response to keyhole limpet hemocyanin p-azophenylarsonate (Ars), we have determined the amino acid and/or nucleotide sequences of several anti-arsonate antibodies of the Ars-A family in the A/J, C.AL-20, and BALB/c strains. These structures have been compared to certain BALB/c anti-phenyloxazolone and anti-levan antibodies previously sequenced and to the A/J V kappa 10-Ars-A genomic sequence (where V kappa = kappa chain variable). These primary structural studies were complemented by Southern filter hybridization analyses utilizing V kappa and kappa chain joining (J kappa) molecular probes. We found a surprising uniformity of structure among these antibody light chains derived from different murine strains. Thus, in contrast to the heavy chain variable (Vh) regions of the Ars-A antibody family where the BALB/c strain lacks the VH gene segment utilized in the A/J Ars-A response, the light chain variable region gene segments at the V kappa 10-Ars-A locus appear to be identical between the two strains.
