[Blood group-specific variability of sialic acid contents in the chorionic gonadotrophin structure].
Low-pressure ion-exchange chromatography was used for isolation of chorionic gonadotropin (hCG) from urine of pregnant women. The purified hCG-preparations from various blood group donors were shown to differ in their sialic acid content. The highly purified hCG-preparations after gel chromatography were analyzed in the reaction of hemagglutination and the preliminary results suggest their blood group specificity.
