title: Antigenic heterogeneity among monoclonal IgM: observations on guinea-pig sera.
abstract: Antisera against purified monoclonal IgM from patients with Waldenström's macroglobulinemia were raised in guinea-pigs. Absorption with normal human serum and heterologous macroglobulinemic serum resulted in an antiserum to a subgroup present in 5 of 54 sera.
