Abstract
Hemolymph from Charybdis japonica and Lymantria dispar, and saline extract from Eunice kobiensis agglutinated human group B erythrocytes specifically. Multiple agglutinins were identified, and independent agglutinins were separated from hemolymph of Charybdis japonica (anti-BCJ+anti-XCJ) and Lymantria dispar (anti-BLD+anti-RLD) by absorption experiments. By the agglutination and agglutination-inhibition experiments with simple sugars, the specificities of the anti-B agglutinins in these invertebrates were found to differ from each other.
