Abstract
Intact human erythrocytes incubated at 37 degrees C, pH7.4, release a sialoglycopeptide similar in its chemical composition, immunological and aggregation properties to the glycopeptide released by isolated 'ghost' membranes. The presence of ATP or reduced glutathione at physiological concentrations in the incubation medium of 'ghost' membranes inhibits this self-digestion process.
摘要
完整的人类红细胞在37摄氏度、pH值为7.4的条件下孵育，会释放出一种唾液糖肽，其化学组成、免疫和聚集特性与分离的“血影”膜释放的糖肽相似。在“血影”膜的孵育介质中，生理浓度的ATP或还原型谷胱甘肽的存在会抑制这种自我消化过程。
