SummaryBlood group H and B substances were extracted from urea-treated human hair of group O and B individuals, respectively, with methanol-ethyl ether (1:1,v/v) and chloroform-methanol (1:1,v/v). The blood group activities of H and B substances were destroyed by H-decomposing enzyme (α-l-fucosidase) fromBacillus fulminans and B-decomposing enzyme (α-d-galactosidase) fromClostridium sporogenes Maebashi, respectively. It is concluded therefore that the extract from the hair of group O contained blood group H-active glycolipid with α-l-fucose as the non-reducing sugar and the one from group B contained blood group B-active glycolipid with α-d-galactose as the non-reducing sugar.ZusammenfassungDas H-blutgruppenaktive Glycolipoid wurde mit Methanoläther (1:1,v/v) und Chloroform-Methanol (1:1,v/v) aus Harnstoff-behandelten Haaren extrahiert. Wenn nach Behandlung der H-Substanz von Haaren mit H-zerstörenden Enzym (a-l-Fucosidase) ausBacillus fulminans H-Aktivität spurlos verschwindet, so kann es sein, daß α-l-Fucose für die H-Aktivität von Haarglycolipoid benötigt wird. Das B-blutgruppenaktive Glycolipoid wurde aus Menschenhaaren extrahiert. Durch Einwirkung von B-zerstörendem Enzym (α-d-Galaktosidase) ausClostridium sporogenes Maebashi auf das B-Glycolipoid aus Haaren, kommt nunmehr die H-Eigenschaft nach Inaktivierung von B zum Vorschein. Darum kann es sein, daß α-d-Glaktose für die B-Aktivität vom Haarglycolipoid benötigt wird.

The genetic determinants responsible for the specificities of somatic antigens of Escherichia coli 2B‐V, O6 and O86, which also have blood group H, A and B activity, respectively, are located near the his locus on chromosomes.
