  • Publication number: 20220240499
    Abstract: A cryopreservative composition includes a sugar component with a total concentration of sugar components in the composition of 300 mM or less; a sugar alcohol component, with a total concentration of sugar alcohol components in the composition of 2 M or less; and at least one of a polymer component and albumin, with the proviso that the composition includes less than a cryopreservative amount of dimethyl sulfoxide (DMSO). A method of cryopreserving a cell includes adding a cell to the cryopreservative composition; freezing the composition; storing the frozen composition; thawing the composition; removing the cell from the thawed composition; and culturing the cell under conditions effective for the cell to remain viable. The freezing may include cooling at a rate of 0.1° C./min to 5° C./min. The method may be performed without a washing step after thawing.

  • Patent number: 9909099
    Abstract: An example includes an apparatus for separating cells from a fluid sample, including a plenum, defining: a centrally located top inlet, and respective side outlets disposed below the inlet and to the side of the inlet; and a bottom outlet disposed below the top inlet, to the side of the two or more outlets, wherein the plenum is configured to receive a fluid and cells suspension through the inlet, and direct it to the bottom outlet, against respective side-walls extending between the bottom outlet and the two or more side outlets, and wherein the distance between each of the two or more side outlets and the bottom outlet is selected to encourage cells to exit through the bottom outlet under a force. Lateral/vertical distance between the inlet and side outlets can provide lateral fluid travel, thereby allowing time for gravity to bias cells toward an outlet.
