Abstract:
Concanavalin A and a mannose-specific lectin could be precipitated specifically from extracts of jack bean and Cajanus cajan seeds, respectively, using metal charged EGTA. Single step purification of the lectins was also possible using iminodiacetic acid-Sepharose charged with metal ions. Nondenaturing electrophoresis in polyacrylamide gel and that performed in presence of SDS ascertained homogeneity of the isolated lectins. The migration behavior of the purified lectins was comparable with those of the lectins purified using alternative procedures.
