Bioprocess development for the production of a recombinant

Vectors for the Glutamine Synthetase (GS) system, first reported in 1987, were adapted to the CHO cell line. CHO-ori. CHO cell line is . established in the laboratory of Theodore Puck at the Eleanor single cell suspension culture using the New Brunswick S41i CO 2 incubator shaker.

CHO cells should be cultured in Ham’s F12K (ATCC suggestion) or DMEM modified with 10% FBS. If cells are not doubling every 14-17 hours, supplement the medium with 1-2% FCS. Subculture Protocol for Answer Chinese Hamster Ovary cells (CHO) have been around a long time, since the 1960s and as with most of the early-cultured cells they are derived from a rodent. Rodent cells were used to create the first homogeneous cell lines and media formulations. Many events occurred to bring CHO cells to the forefront in biotechnology. I know that CHO cells can be adapted for either adherent or suspension culture, depending on the desired application. Have you started using a new batch of flasks or plates recently? If you want This page contained one excellent suggestion and that is to select for cells that do not clump during the passage, by pooling the cells in 15ml of media in a tube and letting the clumped cells to settle down by gravity for 5 minutes and afterwards taking the top 1ml and passaging it and after 20 passages using the exact same technique, you should be able to get single cell suspension.

Subcultivation of CHO cells in suspension culture using the commercial serum-free medium EX-CELL™302, which contained an IGF-1 analog, supplemented with LPA resulted in gradually increasing specific growth rate comparable to the serum-containing medium and in almost the same high antibody production regardless of the number of generations. CHO Cell Culture Medium is appropriate for suspension CHO cells. It is also appropriate for a selection system such as glutamine synthetase (GS), which does not require the selective pressure of hypoxanthine/thymidine (HT)-deficient medium.
