What is Cell Freezing?

Cryopreservation, or cell freezing, is a crucial step of animal cell culture and long-term maintenance, which is different from the process of preserving bacteria and fungi. It is the most effective method of animal cell culture preservation and is accomplished by either a suitable cryogenic agent or liquid nitrogen. It can oftentimes be difficult to maintain cell lines, due to the viability of preserved cell lines, slow growth rates, physiological conditions, cell density and the type of cryoprotectant and freezing technique.
