The polypeptide pattern of red blood cell (RBC) membranes from @entity291 , @entity742 , @entity1641 , @entity95 , @entity840 , @entity35 , @entity19 , analyzed by @entity2975 gel electrophoresis, was compared to @entity1 RBC counterpart. Some qualitative and quantitative differences were noted. Among the high molecular weight components the bands 2.1-2.3 appeared slightly decreased in @entity95 and @entity35 and increased in @entity742 RBC membranes. Band 3 appeared to have a higher molecular weight in the @entity291 , @entity840 and @entity19 RBCs, and a lower molecular weight in the @entity742 RBCs. @entity58345 from the RBC membranes of @entity291 , @entity742 , @entity95 and @entity840 was splitted into two sub-bands, while band 4.2 overlapped with @entity58345 in @entity1641 and @entity840 RBC membranes. There are marked differences in the number and position of bands in the 4.5 region, while band 4.9 is present in higher amounts in @entity1641 , @entity95 and @entity840 RBC membranes. Band 6 ( @entity60251 ) was undetectable in @entity1641 , @entity35 and @entity19 RBC membranes and was decreased in @entity742 , @entity95 and @entity840 . There are also major differences in the region of band 7 and below ("post-7"). Band 8 was undetectable in @entity1641 , @entity291 and @entity840 , and was in higher amounts in @entity35 . A band corresponding to a molecular weight of about 22 kD in the "post-8" region was present only in @entity840 RBC membranes.
