[Erythrocyte vesiculation. 3. Building block analysis of vesicles from preserved blood].

The contents of total protein, haemoglobin, hexose, phospholipid and sialic acid of erythrocytic vesicles prepared from ACD-AG blood samples banked for 6 weeks were analyzed quantitatively. The results were discussed and compared with those of other authors. The bulk of vesicular haemoglobin is not released under hypotonic conditions. It can be determined with the haemiglobincyanide method in the presence of SDS.
