Instructions

  1. Collect culture cells (during logarithmic growth stage) and place 5x105 - 1x107 cells in a cryovial. Centrifuge for 5 minutes at 1,200 rpm.
  2. Add 1 ml of Cos Banker to cell pellet and vigorously mix, then freeze and store at -80°C.
  3. If liquid Nitrogen storage is desired, freeze cells at -80°C first and then transfer to liquid Nitrogen.
  4. To thaw, defrost in 37°C water bath quickly.
    Note: It is ideal to use a logarithmic growth stage culture in order to increase the survival rate when thawed.
