[Immunofluorescence method of detecting cholera enterotoxin].
The quantitative immunofluorescent assay for the determination of cholera enterotoxin is proposed. The assay is based on the selective sorption of cholera enterotoxin by gangliosides incorporated into polyacrylamide granules. The preliminary treatment of gangliosides with neuraminidase enhances the sensitivity of this assay. The assay permits the detection of cholerigen in an amount of 20 ng.
