TL;DR: Through the use of absorbed idiotypic antisera prepared against single isolated monoclonal IgM anti-γ-globulins, partial cross-idiotypic specificity was demonstrated, indicating basic similarities between proteins of a given activity even in unrelated individuals.

TL;DR: It thus appears that for the anti-γ-globulins various levels of selection of light chains are manifest ranging from a preponderance of kappa type, ofKappa III subgroup, of k Kappa III b sub-subgroup and perhaps of still further subdivisions to account for the cross-idiotypic specificity.
