The present invention provides a novel lectin exhibiting high specificity for blood group A sugar chains and Forssman antigen sugar chains. The lectin of the present invention has (1) a molecular weight by SDS electrophoresis of 10,000 to 60,000, and (2) a molecular weight of 60,000 to 100,000 by gel filtration. (3) A lectin derived from the basidiomycete basidiomycete having the characteristics of binding to Forssman antigen sugar chain and A-type sugar chain. [Selection figure] None |
