Ethnicity: Caucasian

Comments: The line is negative for CEA, CSAp and colon antigen 3.

The cells are weakly positive for keratins and vimentin.

Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. 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: Shake flask, pour one-half of the medium into a new flask and add fresh medium to both flasks. Cells remaining attached may be removed （if desired） using a standard trypsin protocol.

Add 2.0 to 3.0 of 0.25% （w/v） Trypsin- 0.53 mM EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed.

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.

Subc*tion Ratio: A subc*tion ratio of 1:5 to 1:10 is recommended

Medium Renewal: Every 2 to 3 days

Preservation: Freeze medium: Complete growth medium supplemented with 10% （v/v） DMSO

Storage temperature: Liquid nitrogen vapor phase

Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2001

recommended serum:ATCC 30-2020
