To begin wash 20 microliters of the whole blood by centrifuging it with one milliliter of PBS at 268 G for three minutes. Then discard the supernatant. Resuspend the resultant red blood cells, or RBCs, in one milliliter of PBS by gentle pipetting.
Wash the RBCs again and discard the supernatant as demonstrated previously. Using a 10-microliter micro-pipette tip, extract five microliters of RBC pellet and fully dispense it into one milliliter of the dielectrophoresis, or DEP, medium. Wash the cells and discard the supernatant as demonstrated.
Resuspend the pelleted RBCs in one milliliter of DEP medium by gentle pipetting. After washing the cells and discarding the supernatant, pipette two microliters of RBC pellet into 500 microliters of DEP medium. Confirmed the concentration of the resulting cell suspension using a standard cell counting slide.
