Relationships between Na+,K+-ATPase, sialic acid content and fluidity in rainbow trout density-separated erythrocytes

A correlation was found between membrane fluidity, sialic acid (SA) content and Na+,K+-ATPase activity in the rainbow trout Oncorhynchus mykiss erythrocyte membrane and this suggests that alterations in erythrocyte Na+,K+-ATPase activity might be caused by modified membrane fluidity through modified SA content.
