the analysis of groups of independently expressed , highly homologous v kappa regions , namely v kappa 17s29.1 and v kappa 2s1.3 as one and v kappa 7s34.1 and v kappa 22s25.1 as a second group , offers the possibility of estimating the minimal number of v kappa germline genes involved in the immune response to the structurally defined streptococcal group a polysaccharide antigen .
