CHO Chemically Defined Media
Suspension Culture (Expression & Production)
CH300 mdium (CD medium), liquid or powder
For CHO cells "CHO-K1, CHO-S, DG44, DXB11, etc."
CH300 medium is a chemically defined medium / serum-free medium optimized for the high production of recombinant proteins in Chinese hamster ovary (CHO) cells, such as CHO-K1, CHO-S, DG44, and DXB11 cells. The medium contains no proteins, hydrolysates, or human/animal-derived components. All components have a known chemical structure.
Suspension CHO-K1 cells were cultured with disposable Erlenmeyer flasks under the following conditions.
CH300/CH300AZ medium leads to the high performance similar to Thermo CD OptiCHO medium in cell growth for CHO-K1 cells.
< Culture conditions >
(1) Seeding cell density:2 x 10e5 cells/mL.
(2) Shaker culture:125 rpm, 37℃, 8% CO2.
(3) Culture volume:30 mL with L-alanyl-L-glutamine.
Suspension CHO-S cells were cultured with disposable Erlenmeyer flasks under the following conditions.
CH300/CH300AZ medium leads to the high performance similar to Thermo CD OptiCHO medium in cell growth for CHO-S cells.
< Culture conditions >
(1) Seeding cell density:2 x 10e5 cells/mL.
(2) Shaker culture:125 rpm, 37℃, 8% CO2.
(3) Culture volume:30 mL with L-alanyl-L-glutamine.
CH300/CH300AZ medium exhibits the higher performance in human IgG production compared to other company medium without inhibiting the transfection assay.
< Culture conditions >
(1) Seeding cell density:2 x 10e6 cells/mL, >95% viability.
(2) Static culture:37℃, 5% CO2.
CH300/CH300AZ medium exhibits the equal or higher performance in gene expression compared to other campany medium without inhibiting the transfection assay.
< Culture conditions >
(1) Seeding cell density:6 x 10e6 cells/mL, >95% viability.
(2) Shaker culture:125 rpm, 37℃, 5% CO2.
(3) Transfection reagent:Gxpress CHO TF Reagent (GMEP Inc.).
