FreezingandThawingofMammalianCellLines

For long term storage of myeloma cells, hybridoma cells, T cells, and other mammalian cell lines in liquid nitrogen, and restoring them in culture.FreezingPreparationCells are to be frozen in liquid nitrogen, so make sure your canisters are relatively full of nitrogen and you have room. Cells should be healthy (>90% viability) and growing in log phase. You will also require sterile 1 mL cryo-vials; they have a scr......阅读全文
