When making hybridomas it is desirable to lyse the RBCs and leave the
lymphocytes viable.  We resuspend the cell pellet from a single spleen in 5
ml of ice cold 0.75% ammonium chloride, on ice, five minutes, then pellet
the cells, discard the now red supernatant, and resuspend the cell pellet in
normal medium, or buffered saline.  Virtually all the RBCs are gone and the
lymphocytes are still viable.
