title: Biochemical characterization of density-separated trout erythrocytes.
abstract: 1. A discontinuous gradient in the region of 45-65% "Percoll" has been utilized for the separation of trout erythrocytes. Three different fractions were obtained. 2. We have evaluated antioxidant enzyme activities and membrane fluidity. The results indicated that catalase and glutathione peroxidase activities increased with the density of the fraction while the membrane fluidity was unchanged. 3. The observed results show a marked difference between nucleated (fish) and unnucleated (human) separated erythrocytes.
