title: A method to maintain mammalian cells for days alive at 4 degrees C.
abstract: This paper describes a method for the temporary storage of cultured cells. Cells from recently completed cell monolayers were trypsinized and then centrifuged. After centrifugation, the supernatant and pellet were kept at 4 degrees C for one week. After storage, the supernatant was discarded, the cells were resuspended and used for seeding new flasks and for titration of virus. The cells not only remained viable, but also rapidly formed new monolayers and allowed immediate infection and growth of viruses. We conclude that this method can be a helpful asset to cell culture experiments.
