5.01 Harvest cells from the interface of the ficoll layer and wash the cells 2x with RPMI
1640 medium. On the last wash transfer cells to a 15ml conical test tube, obtain an
accurate, viable cell count, and then spin at 800xg for 10 min. Remove all of the
RPMI medium.
5.02 Resuspend the pellet in 2.5ml of a 0.1% BSA/PBS solution at room temperature.
This is to wash out any remaining RPMI and to get the cells prepared for staining.
5.03 Centrifuge cells at 800xg for 10 min. and decant.
