Polymorphism of A, B and H substances in human urine
Journal of Chromatography
|January 1, 1978
Abstract:
The gel-chromatographic behavior of A, B and H substances from urine was examined and compared with that of previously described AHB salivary fractions. Urinary fractions 1 and 2 exhibited a molecular size smaller than those of salivary fractions 1 and 2. In the urine of 52 subjects a polymorphism of A, B and H substances, with four main types, was observed which is independent of the salivary one and of the so-called secretor and nonsecretor status.
