Summary
Blood group substances were extracted from erythrocytes of blood groups a1 and A2 and seperated using HPTLC. Identification of blood group A was carried out on the chromatogramm using the PAP-technique. The specific demonstration of the serologically active glycosphingolipids allowed a comparison of the a1 and A2 blood group substance bands. The difference between the a1 and A2 Substances appears to be only a quantitative one.
Zusammenfassung
Aus Erythrozyten der Blutgruppen a1 und A2 wurden Blutgruppensubstanzen extrahiert und mittels HPTLC aufgetrennt. An den Chromatogrammen wurde der A-Nachweis mittels PAP-Technik durchge-führt. Die spezifische Darstellung der serologisch aktiven Glykosphingoli-pide erlaubt die Banden der A1 und A2-Blutgruppensubstanzen zu verglei-chen. Die Unterschiede zwischen den A1 und A2-Substanzen scheinen nur quantitativer Art zu sein.
