Genetic polymorphism of IgG in the mink. V: Two new genetic markers of the lambda light chains of mink immunoglobulins, L4 and L5

Two new allotypes of light (L) chains IgG, L4 and L5, were identified in the mink with dispecific antiserum produced by immunization with allogenic IgG. By means of hybrid IgG molecules and proteolytic fragments, L4 and L5 were localized on the C region of the L chain. L4 and L5 occurred frequently in the three mink populations studied and L4 and L5 are inherited independently of the known mink Cγ allotypes
