George Yerganian's laboratory at the Boston Cancer Research Foundation and used it to derive the original Chinese hamster ovary (CHO) cell line. Since then, 

The cell line was derived from CHO-K1 cells (see ATCC CCL-61) treated with mutagen (ethylmethanesulfonate) and screened for mutants defective in proteoglycan synthesis. To ATCC Valued Customers, ATCC stands ready to support our customers’ needs …

CHO cell line 3-631-436 AM5 ATCC ® PTA-8369™ U.S. Patent Num 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. CHO Subculture Protocol (adherent) CHO cells grow quickly and easily and cell doubling time is 14-17 hours. This line is a mutant clone derived from the parental CHO clone Pro-5 (a proline auxotroph, see ATCC CRL-1781) by selection for resistance to wheat germ agglutinin. To ATCC Valued Customers, ATCC stands ready to support our customers’ needs during the coronavirus pandemic. The CHO-K1 cell line was derived as a subclone from the parental CHO cell line initiated from a biopsy of an ovary of an adult Chinese hamster by T. T. Puck in 1957. The cells require proline in the medium for growth.

.. This line is a derivative of the CHO cell line. The AA8 line has 21 chromosomes and is heterozygous at the aprt locus. The line is useful for gene mutation assays and is the parent line for a series of repair deficient mutants (see ATCC CRL-1860, ATCC CRL-1861, ATCC CRL-1862, ATCC CRL-1865, ATCC CRL-1866 and ATCC CRL-1867). Complete Growth Medium. FreeStyle™ CHO-S Cells are part of the FreeStyle™ MAX Expression System, which is a breakthrough technology for rapid and high-yield mammalian protein production.

Both cell lines were cultured in alpha-minimal essential medium (αMEM; Gibco-BRL, New York) supplemented with 10% (vol/vol) fetal calf serum (JRH Biosciences, Kansas), 4 mM l -glutamine, 100 IU of penicillin, 10 μg of streptomycin/ml, nonessential amino acids (Gibco-BRL), and 50 μM β-mercaptoethanol. Cell Lines CHO 5/9 m alpha 3-18 (M-CSF) cells (ATCC #CRL-10154) were obtained from the American Type Culture Collection (ATCC). Cell line CHO-IgG is a proprietary clone expressing a recombinant antibody.

Cell Lines. CHO 5/9 m alpha 3-18 (M-CSF) cells (ATCC #CRL-10154) were obtained from the American Type Culture Collection (ATCC). Cell line CHO-IgG is a.

After 30 min, buffer was removed and its radioactive content was determined by gamma radiation counting. Error bars, standard deviations. Switching from 293 to CHO cells during drug development doesn't have to create uncertainty. Now there's a better way. The Gibco ExpiCHO Expression System is a completely optimized system consisting of ExpiCHO-S(TM) cells that have been adapted to high-density, serum-free suspension culture in ExpiCHO(TM) Expression Medium, along with specially designed transfection reagents and enhancers, that 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.
