Abstract: Disclosed herein are cartridges for transfecting cells and/or generating clonal populations of cells comprising: a) a first compartment configured for performing cell transfection, wherein the first compartment comprises a first inlet configured for introduction of a cell sample; b) a second compartment configured for performing cell selection, wherein an inlet of the second compartment is operably coupled to an outlet of the first compartment, and wherein the second compartment further comprises at least one optically-transparent wall and an outlet that is operably coupled to an intermediate cell removal port; and c) a third compartment configured for performing cell expansion, wherein an inlet of the third compartment is operably coupled to the outlet of the second compartment.

Abstract: A system for processing cells is provided. The system can include a cell culture container, a fluid handling device, and one or more removable cell processing modules for performing one or more cell processing processes. The one or more removable cell processing modules can include a fluid handling pathway. The one or more removable cell processing modules can be fluidly connected to the cell culture container and the fluid handling device via a receptacle in which the cell processing modules may be inserted. The system can be a closed system.
