Provided are compositions comprising a population of cells that are amenable to freezing or lyophilization while maintaining viable cells. The compositions comprise a monosaccharide, urea and, in some embodiments, a bulking agent. Also provided are methods for preparing and storing cells via freezing or lyophilization in a manner that allows cells to remain viable during storage.

The present disclosure is directed to the organic growth and phasing design for a system for the industrial growth of biologics. A system may include a number of subsystems, such as a buffer distribution subsystem, a media preparation subsystem, a bioreactor subsystem, a harvest subsystem, and/or a purification subsystem. The subsystems may be highly interconnected for flexible process flow design. Additionally, the subsystems may be constructed with a total output capacity with a total number of equipment stations and operated at a lower output capacity with fewer than the total equipment stations to maintain headroom for growth in phases.

The present invention is in the field of recombinant biotechnology, in particular in the field of protein expression. The invention generally relates to a method of expressing a protein of interest (POI) from a host cell. The invention relates particularly to improving a host cell's capacity to express and/or secrete a protein of interest and use of the host cell for protein expression. The invention also relates to cell culture technology, and more specifically to culturing cells to produce desired molecules for medical purposes or food products.

Described herein are compositions and methods for identifying, selecting, or culturing cells comprising a subject nucleic acid sequence of interest. Generally, a nucleic acid comprising a subject nucleic acid and a sequence encoding an enzyme molecule involved in biosynthesis of an amino acid is introduced into a cell. The cell is then grown on media lacking the amino acid, such that cells comprising the introduced nucleic acid are capable of growth. In some instances, the cell further comprises an inhibitor of the enzyme molecule to increase the stringency of the selection.

Disclosed are genetic control circuits, cells, and methods that use a repressor polypeptide to reduce the transcription rate of an exogenous therapeutic polypeptide encoding gene in response to a change in condition.

A predictive model is described that can predict parameter concentrations in the future based on initial, measured concentrations and historical data. A plurality of multivariate techniques can be used to construct the predictive model capable of forecasting concentrations over multiple and diverse cell lines. The predictive model is also scalable. In one embodiment, a future lactate concentration trajectory is determined and at least one condition within a bioreactor is changed or modified to maintain lactate concentration within desired ranges.

The present disclosure features methods and compositions for increasing the amount of products of cellular metabolism, e.g., proteins, by lowering the temperature of cells expressing the product at one or more steps while culturing the cells, expressing the product, and/or recovering the product.

The present disclosure provides an ultraviolet light filter for use in photostability testing chambers, and in particular, filters that are designed to allow for air ventilation and maintenance of desired temperatures at the sample level during light exposure testing.

Described herein are methods for enhancing the nuclear reprogramming of somatic cells to become induced pluripotent stem cells. In particular, the methods disclosed herein involve the use of damage-associated molecular pattern molecules (DAMP). In certain embodiments the DAMPs are aluminum compositions such as aluminum hydroxide. Such DAMPs have unexpectedly and surprisingly been found to enhance the nuclear reprogramming efficiency of the reprogramming factors commonly used to induce somatic cells to become induced pluripotent stem cells. Accordingly, this disclosure describes methods of nuclear reprogramming as well as cells obtained from such methods along with therapeutic methods for using such cells for the treatment of disease amendable to treatment by stem cell therapy; as well as kits for such uses.
