The protein contains the p30 (SAG1) immunodominant regions, amino acids 45-198. The protein is purified by proprietary chromatographic technique.

Background: Toxoplasma gondii is an obligate intracellular protozoan parasite that infects all warmblooded animals, including humans, and causes toxoplasmosis. SAG1, the major surface molecule of Toxoplasma gondii, is an important attachment ligand for the host cell. It is a highly immunogenic protein which has generated great interest as a diagnostic reagent, as a potential subunit vaccine, and for its role in invasion.

Antigen in ELISA and Western blots, excellent antigen for detection of Toxoplasma gondii with minimal specificity problems.

Specificity: Immunoreactive with sera of T. gondii- infected individuals.
