the present work demonstrates that the injection of cysteine hydrochloride , a reducing agent , into animals has a pronounced effect on the character of immune response to proteinaceous antigen ( bovine serum albumin ) : the formation of antibodies is enhanced , the synthesis of igm is prevented from being changed over to the synthesis of igg , the time of the circulation of free antigen is reduced and the time of their circulation in the blood is increased .
