Methods for harvesting mammalian cell cultures

The invention provides methods and materials for culturing mammalian cells and harvesting recombinant protein.

Bioreactor System
20220033769 · 2022-02-03 ·

A three dimensional cell culture and bioreactor system is provided. The system comprises one or more cell culture chamber. Each cell culture chamber comprises an inlet port and an outlet port in fluid communication with the cell culture chamber. The cell culture chambers may be segregated or in fluid communication with one another. The systems may be used to conduct drug efficacy test, isolate certain cell types from a complex tissue sample of multiple cell types, allow for the ex vivo culturing of patient tissue samples to help guide the course of treatment, and conduct co-culture experiments.

Acoustic perfusion devices

Acoustic perfusion devices for separating biological cells from other material in a fluid mixture are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid mixture is being drawn.
