[A1 and A2 blood group substances: are there structural differences?].
Blood group substances were extracted from erythrocytes of blood groups A1 and A2 and separated 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.
