Isolation and characterization of a lectin from Sarcocystis gigantea.
A hydrophobic, galactose-specific lectin was isolated by means of affinity chromatography from Sarcocystis gigantea. Adsorbents with different spacer lengths were tested. S. gigantea lectin differs from sheep muscle lectin in the spacer length needed for adsorption. Sodium dodecyl sulfate-gel electrophoresis of the S. gigantea lectin revealed a subunit size about 19 kDa and the presence of disulfide cross-linked dimers. The lectin is present in high concentration in cystozoites, cyst fluid and cyst wall material.
