Wash your cells and resuspend in 70% RPMI, 20% FCS and 10% DMSO in a 
concentration of 1x10e7 cells/ml. Aliquot in 1 ml per cryotube. Place tubes in 
a special container (Cryo Freezing Container, Nalgene) with 2-propanol and 
place this container at -80°C. Temperature will decrease approx. 1°C per min. 
After 2 h place tubes in liquid nitrogen.

Good luck.
