that a receptor for complement is involved in binding the guinea-pig agab : c ' complexes is supported by the observations that : a ) guinea-pig complexes , which were not treated with a serum source of complement or which were treated with either fresh serum in the presence of edta or with heat-inactivated serum , do not bind to the t lymphocytes , and b ) heat-aggregated human gamma globulin , which effectively inhibits binding of mouse agab complexes to the afcr gamma , has no effect on the binding of guinea-pig agab : c ' complexes to the t lymphocytes .
