title: Erythrocyte behavior in free-flow electrophoresis is independent of erythrocyte age.
abstract: Enzyme activities (acetylcholinesterase, fluorescein diacetate hydrolase, superoxide dismutase), membrane protein band 4.1a/4.1b ratio and density of various fractions of rabbit erythrocytes separated did not show differences between various fractions of erythrocytes separated by free-flow electrophoresis. Also, electric field deflection of lightest and densest fractions of erythrocytes did not differ. These results point to the lack of changes in surface charge density during in vivo erythrocyte aging.
