Abstract
A diagnostic EIA system for the detection of antibacterial antibodies in diphtheria infection has been developed. As antigen, homogeneous membrane protein (mol. wt. 64 KD) obtained from Corynebacterium diphtheriae cell walls has been used. This protein antigen has been prepared with the use of nonionic detergent NP-40.
