Hemolysis of human erythrocytes is a new bioactivity of gangliosides
Using sheep erythrocytes and liposomes, an inhibitory effect of gangliosides has been shown on the activation of the alternative pathway of complement. However, in studies using human erythrocytes, we found that gangliosides had hemolytic activity that was possibly mediated through activation of the alternative pathway. Pretreatment of human erythrocytes obtained from healthy volunteers or paro...
متن کاملMyosin from human erythrocytes.
We have purified myosin from human erythrocytes using methods similar to that for other cytoplasmic myosins with a yield of about 500 micrograms/100 ml of packed cells. It consists of a 200-kDa heavy chain and light chains of 26- and 19.5 kDa and therefore differs from the isozyme in platelets which has light chains of 20- and 15 kDa. At low ionic strength, the myosin forms short bipolar filame...
متن کاملa new method for the purification of cu-zn superoxide dismutase from human erythrocytes
the human erythrocyte is a rich raw material for the purification of cu-zn superoxide dismutase (sod). we applied a simple and rapid procedure for the purification of sod from human erythrocytes by ion exchange chromatography. the purified sod had a specific activity of 2285.6 u/mg protein and gave a single band on polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (sd...
متن کاملGangliosides of human kidney.
Five gangliosides isolated from human kidney have been characterized. The two main fractions were shown to be typical extraneural gangliosides in having lactose as their neutral carbohydrate moiety. Their structures were identified as: AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-8)AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer. The two main hexosamine-containing gangliosides are str...
متن کاملGangliosides of Human Kidney*
Five gangliosides isolated from human kidney have been characterized. The two main fractions were shown to be typical extraneural gangliosides in having lactose as their neutral carbohydrate moiety. Their structures were identified as: AcNeu(Lu2-3)Gal(/31-4)Glc(/3l-l)Cer and AcNeu(cuZ8)AcNeu(cu2-3)Gal(/31-4)Glc(/3l-l)Cer. The two main hexosamine-containing gangliosides are structurally related ...
