title: Quantitative analysis of an idiotypic determinant of light chains of normal human IgG and IgM.
abstract: Normal light chains of human IgG and IgM were analyzed for the presence of the idiotypic determinant of light chains identified by anti-"a". A quantitative evaluation indicated that this marker of the variable region was present in light chains obtained from IgG and IgM; however, light chains reacting with anti-"a" were preferentially associated with IgG molecules.
