Hypersensitivity to a synthetic polypeptide: induction of a delayed reaction.
A multichain copolypeptide, p(Tyr,Glu)-pAla--pLys, induced in guinea pigs a prolonged state of delayed hypersensitivity not associated with detectable circulating antibodies. Cross reactions of the delayed type were observed with chemically related polypeptides.
