Abstract

Cross-linking semipurified and purified heat-stable enterotoxin (2023 ST) to carrier proteins with glutaraldehyde pigs and rabbits were immunized. With ST antisera thus raised, a relatively simple, two-step method for isolation of ST is described. The method involved immunoadsorbent column chromatography procedure, and elution of the retained material with 6 M urea at pH 3.0 yielded purified ST with enterotoxin activity, controlled in suckling mouse test. ST purity was checked with a special staining technique in PAGE, anionic-exchange chromatography and immunodiffusion.
