igm reactivity with the 55- , 70- , and 105- to 110-kda antigens by blotting was highly correlated with antilymphocyte antibody activity in complement-dependent cytotoxicity assays ( fisher 's p less than 0.001 ) , and paralleled flow microfluorimetric and microcytotoxicity quantitation of igm antibody activity in serial observations of individual patients studied during different phases of disease activity .
