The induced protein was isolated from inclusion bodies by a simple solubilization-renaturation procedure and purified by ion exchange chromatography on Q-Sepharose to over 95% pure monomeric protein.Recombinant A-protein was compared by biochemical, immunological and molecular methods with the A-protein isolated from atypical A.salmonicida bacterial cells by the glycine and the membrane extraction methods.\u003c\/p\u003e\n\u003ch3\u003eProduct format\u003c\/h3\u003e\n\u003cp\u003eProvided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development.
