title: Studies on the specificities of various anti-H reagents.
abstract: Four different eel serum samples and the lectins Cytisus sessilifolius and Evonymus europaeus were examined for their capacities to react with a number of preparations which show O(H) blood group-like activity. Some similarities and major differences between the anti-H reagents were observed in experiments where the "H-like" activities of invertebrate extracts and blood group substances were compared. A comparison of the reactivities of eel sera, catfish anti-H sera and 4 anti-H lectins with a number of different "H-like" preparations is summarized. Data obtained from preliminary sugar analyses of preparations isolated from 5 different invertebrate species studied is presented.
