Abstract: The present disclosure provides, among other things, a cryopreservation medium comprising a cryoprotectant, an albumin, a disaccharide and a non-pyrogenic and isotonic crystalloid solution. The disclosure also provides, among other things, a cryopreservation medium for cryopreserving immune cells, the medium comprising: human serum albumin (HSA), sodium chloride, sodium gluconate, sodium acetate trihydrate, potassium chloride, magnesium chloride, dimethyl sulfoxide (DMSO), and a trehalose. The present disclosure also provides, a method of cryopreserving immune cells, transporting and subsequently administering such immune cells to a patient in need thereof.

Abstract: The present disclosure provides, among other things, a method of cryopreserving and thawing cells that results in the thawed cells having high cellular viability and functionality post-thawing. In some embodiments, a large-scale method of cryopreserving cells is provided, the method comprising: (a) contacting the cells with a cryopreservation medium; (b) cooling the cells to ?80° C. at a controlled rate to minimize latent heat of fusion; and (c) storing the cells in liquid nitrogen vapor phase, thereby cryopreserving the immune cells.

Abstract: In vitro CART characterization assays and methods of using them are disclosed.
