Inhibitory effect of diphtheria toxin on amino acid incorporation in Escherichia coli cell-free system.

abstract：:A method of assay of immunogenic potency of the cholera gut toxin is described; it is based on the relation of dose of antigen to neutralizing antibody titer produced in the rabbit under defined conditions and allows quantification of immunogenicity as immunogenic units per milligram of protein. Evidence, based on imm...
