[An immunoenzyme method of detecting Vibrio cholerae cytolysin].

Abstract

Enzyme immunoassay was used in detection of V. cholerae cytolysin. Conjugate of immunoglobulins to purified cytolysin with horseradish peroxidase was used, obtained by the periodate technique. The method sensitivity is 2 ng/ml of purified cytolysin. The results of hemolytic activity measurements in supernatants of 40 V. cholerae strains and enzyme immunoassay findings were in high correlation.
