Isolation: Isolation date: 1957

Applications: transfection host

Virus Resistance: poliovirus 2; modoc virus; Button Willow virus

Cytogenetic Analysis: Chromosome Frequency Distribution 50 Cells: 2n = 22. Stemline number is hypodiploid.

Gender: female

Comments: 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 ***** Chinese hamster by T. T. Puck in 1957.

The cells require proline in the medium for growth.

Propagation: CHO-K1細胞ATCC complete growth medium: The base medium for this cell line is ATCC-formulated F-12K Medium, Catalog No. 30-2004. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.

Temperature: 37.0°C

Subculturing: Protocol:

Remove and discard culture medium.

Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.

Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).

Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37?C to facilitate dispersal.

Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.

Add appropriate aliquots of the cell suspension to new culture vessels.

Incubate cultures at 37?C.

Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended

Medium Renewal: Once or twice between subculture

Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5%

Storage temperature: liquid nitrogen vapor phase

Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2004

recommended serum:ATCC 30-2020
