[Erythrocyte membrane proteins during exposure to moderately low temperatures].

The electrophoretic analysis of erythrocyte membrane proteins after cooling the reconstituted cells to moderately low temperatures (-30 degrees divided by -70 degrees C) has demonstrated that freezing at slow rates results in an increase in the oligomerization capability of spectrine, the main membrane skeleton protein and band 3 protein under the effect of diamide--a thioloxidizing agent. The data obtained testify to the fact that the membrane is a relatively cryoresistant cellular component at more rapid cooling rates in the presence of cryoprotective compounds.
