<p>A process for isolating the carbohydrate fraction (oligosaccharides) from cell tissue with degradation of the glycoconjugates, the cell tissue being treated with a reagent containing or consisting of trifluoroacetic acid anhydride, and the carbohydrates being released under conversion to trifluoracetates, which are optionally detrifluoroacetylated. Starting from erytrocyte membranes oligosaccharides possessing blood group specificity can be recovered, and such oligosaccharides are useful for blood group determination. </p> |
