CryopreservationofCellLines
AimThe protocol below describes the use of passive methods involving an electric -80ºC freezer for the cryopreservation of cell cultures. ECACC routinely use a programmable rate controlled freezer (Planer Series Two) from Planer Products. This is the most reliable and reproducible way to freeze cells but as the cost of such equipment is beyond the majority of research laboratories the methods below are described in d......阅读全文
