Prepare the cell suspension and determine the cell concentration.• Dilute the cell suspension in 1:1 ratio with freezing medium (final concentration approximately 1 X 106 – 1 X 107cells/ml is desired). • Dispense the cell suspension into prelabeled cryovial and place the vial in -80°C freezer overnight (temporary storage).• Transfer the cryovial into liquid nitrogen cryotank for long term storage the following day.• After day 3, determine the cell concentration in the freezing medium andcompare with that of the stock concentration.
