I am trying to isolate RBCs from blood, nearly 300mL. Can anyone suggest the best protocol for it?
I am following slow-speed centrigugation method with washing the cells with cold PBS. Overtime I wash the cell I lose RBCs significantly from the pellet; they are may be ruptured. Because I see red supernatural with decrease volume of pellet in every step. And keep on loosing RBCs.
So I decrease the no. of washing. But I need suggestions...!!!
