Intact human erythrocytes were exposed to low concentrations of glutaraldehyde. After washing and subsequent lysis of the cells, glyceraldehyde 3-phosphate dehydrogenase activity is found to be associated with a membrane fraction and cannot be eluted by salt treatment. Lactate dehydrogenase activity is associated with a supernatant fraction under the same conditions. Preincubation of the intact cells under conditions designed to increase internal NADH concentrations, leads to a lower membrane-associated activity of glyceraldehyde 3-phosphate dehydrogenase after lysis.
完整的人红细胞暴露于低浓度的戊二醛中。在洗涤并随后裂解细胞后,发现3-磷酸甘油醛脱氢酶活性与膜部分相关,并且不能通过盐处理洗脱。在相同条件下,乳酸脱氢酶活性与上清液部分相关。在旨在增加细胞内NADH浓度的条件下对完整细胞进行预孵育,会导致裂解后3-磷酸甘油醛脱氢酶的膜相关活性降低。
