Method and device for measuring process parameters in liquid cultures

A method for measuring process parameters in liquid cultures in a plurality of microreactors of at least one microtiter plate includes continuously agitating the liquid cultures using an orbital agitator at least until the reaction is completed in all the microreactors. In order to allow process parameters also of such substances which themselves do not have any fluorescence activity to be measured with relatively low complexity and within a short time, 2D fluorescence spectra are recorded in a plurality of in particular different liquid cultures in the microreactors of agitated microplates. A device for carrying out the method is also disclosed.

Cell culture device

Provided is a cell culture device that has a simple structure and ensures sufficient nutrient supply to cells and oxygenation of the cells to thereby enable mass cell culture. The cell culture device comprises: a cell culture container which is an approximately cylindrical body provided with a flat bottom part at the lower end; a dish-shaped body having an approximately disc shape which is provided with a plurality of magnetic attraction members, said magnetic attraction members being positioned in the circumferential part at equal intervals, and horizontally disposed in a non-contact state within a hollow space inside the cell culture container; and a cyclic body which is provided with a plurality of magnetic attraction members and positioned outside the cell culture container so that the cell culture container is located within the cycle thereof. The cyclic body and the dish-shaped body move vertically in magnetic conjunction to thereby agitate a medium and supply nutrients to cells.

Cell expansion

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), helper, naïve, memory, or effector, for example.
