The invention relates to a method of increasing the yield of virus, virus particles, or viral vectors from host cells in a bioreactor. The invention provides a reproducible and robust method and system of determining and controlling the optimal time of infection of host cells using a correlation of process air parameters including Air flow, O.sub.2 flow, and respective trends thereof resulting in increased virus yield.

A process and system for efficiently producing reference data that can be fed into a predictive model for predicting quality attribute concentrations in cell culture processes. A perfusion bioreactor is operated at pseudo-steady-state conditions and one or more attribute influencing parameters are manipulated and changed over time. As the one or more attribute influencing parameters are manipulated, one or more quality attributes are monitored and measured. In one embodiment, multiple quality attributes are monitored and measured in parallel. The quality attribute information is recorded in conjunction with the changes in the attribute influencing parameters. This information is then fed to the predictive model for propagating cell cultures in commercial processes and maintaining the cell cultures within desired preset limits.

The present technology is generally related to storage structures for cell engineering systems. The storage structures allow for multiple automated cell engineering systems to be held via a single structure, and presented to a user when desired or needed for direct access to the cell engineering system, and then returned to a storage or working position. Many storage structures can be arranged together in a clinical or hospital setting, or other cell therapy engineering manufacturing environment.

A bioreactor has a container, an end plate, an agitator, a drive unit, and at least one field device arranged in the interior, field device electronics, a data transmission unit arranged on the end plate, and a motor head piece coupled in terms of energy to the drive unit. At least one communication unit is coupled in terms of signaling to the motor head piece and includes an adapter piece, having adapter electronics which are electrically connected to the field device electronics of the field device, and a communicator piece. The adapter piece and the communicator piece are separate components which can be coupled to one another, wherein the motor head piece is a separate component which can be coupled to the communication units.

A multi-chamber single-use bioreactor for cell culture expansion has bag assembly and a rigid support structure defining a bag receiving space. The bag assembly disposed in the bag receiving space of the rigid support structure and supported by the rigid support structure. The bag assembly has at least a first flexible bag and a second flexible bag. The first bag defines a first reaction chamber, and the second bag defines a second reaction chamber. The first reaction chamber has a first volume, a first inlet, and a first outlet, and the second reaction chamber has a second volume different from the first volume, a second inlet, and a second outlet. The second inlet of the second bag is fluidically connected to the first outlet of the first bag so liquid in first reaction chamber can be transferred to the second reaction chamber.
