Blutgruppen-ähnliche substanzen in einigen marinen invertebraten. IV. H-und A-ähnliche substanzen,agglutinine und präzipitine: Ihre verteilung bei Cerianthus sp.

In tentacles and other parts of Cerianthus sp., besides a protease, a strong agglutinin has been found which agglutinates red cells of different origin and which shows an antigalactose specificity. In gonads and mantle mucus, a Blood-Group-H-like material could be demonstrated. The agglutinin is an acid protein, and can be precipitated by base polymers. For tentacles, a precipitin with anti-galactogen specificity is described and analysed. In the mantle, the commensal Phoronis australis was discovered which contained material similar to human blood, Group A.
