Cell bank
A cell bank is a facility that stores cells of specific genome for the purpose of future use in a product or medicinal needs. They often contain expansive amounts of base cell material that can be utilized for various projects. The advantages of cell banks is that the facilities will include a "detailed characterization of the cell line" and will have a "decrease in the likelihood and an increase in the detection" of cross-contamination of a cell line.
==Storage==
Before putting the donated cell lines into storage, they are first proliferated and multiplied into a large number of identical cells before being stored in a number of cryovials. These cryovials are then placed into a tray, which is labeled with the genetic line data and then they are all frozen in "the liquid or vapor phase of liquid nitrogen typically between -196 and -70 degrees Celsius."〔 This temperature serves to stop all cell growth within the cryovials and preserves the cell lines. This stopping of the genetic line's growth is especially important for "non-continuous" cell lines that have a "limited number of cell divisions" before dying out.
