Duty cycle for cell culture systems
11566217 · 2023-01-31 · ·

An automated cell culture system with one or more pumps configured to operate on a duty cycle prevents excess heat generation, allowing the cell culture system to operate inside a conventional incubator without overheating. The duty cycle involves switching the pump between on and off modes. By running pumps for a short period of time and then shutting them off, less heat is produced. To account for the reduced pumping time during the cycle, the pump can be run at a higher flow rate while it is on, so that the average flow rate over the course of the cycle is not reduced. Systems of the invention employ duty cycles in which the on-cycle is shorter than the off-cycle, and particularly where the on-cycle is less than 20% of the duration of the entire duty cycle.

METHODS FOR SEPARATING SUSPENSIONS USING SINGLE-USE CENTRIFUGE CONTAINERS

A method for separating a suspension includes dispensing a liquid suspension into a compartment of a first bag assembly. The first bag assembly is then rotated using a centrifuge so as to at least partially separate the suspension, the first bag assembly being disposed within a first insert that is housed within a first cavity of a rotor of the centrifuge, the first insert having an annular lip portion that freely projects out of the first cavity of the rotor by a distance of at least 1 cm.

Reversible liquid filtration system

A reversible liquid filtration system for cell culture perfusion comprises: a bioreactor vessel (B4), for storing the cell culture (L4); a perfusion pump (P7), comprising a reciprocable element (P71) which is movable in opposing first and second pumping directions (dF, dR); a filter (F4); and first and second bi-directional valves (BV1, BV2), each selectively controllable between open and closed positions. The perfusion pump (P7), the filter (F4), and the first and second bi-directional valves (BV1, BV2), together comprise a fluidic circuit in communication with the bioreactor vessel (B4). The bi-directional valves (BV1, BV2) are controllable to open and close in co-ordination with the reciprocating perfusion pump (P7), in order to enable both a two-way filtering flow around the fluidic circuit and also an alternating filtering flow between the bioreactor vessel (B4) and the perfusion pump (P7).

Expanding cells in a bioreactor

Embodiments described herein generally provide for expanding cells in a cell expansion system. The cells may be grown in a bioreactor, and the cells may be activated by an activator (e.g., a soluble activator complex). Nutrient and gas exchange capabilities of a closed, automated cell expansion system may allow cells to be seeded at reduced cell seeding densities, for example. Parameters of the cell growth environment may be manipulated to load the cells into a particular position in the bioreactor for the efficient exchange of nutrients and gases. System parameters may be adjusted to shear any cell colonies that may form during the expansion phase. Metabolic concentrations may be controlled to improve cell growth and viability. Cell residence in the bioreactor may be controlled. In embodiments, the cells may include T cells. In further embodiments, the cells may include T cell subpopulations, including regulatory T cells (Tregs), for example.
