by using both pulse labeling of nascent rna chains and lactoperoxidase-catalyzed cell surface radioiodination , we examined both the de novo synthesis of mrna for gamma-chains and the expression of membrane igg ( migg ) on cells which had been stimulated with lps plus a t cell supernatant ( sn ) containing a b cell differentiation factor for igg1 ( bcdf gamma ) .
