Comments: WiDr細胞Although deposited with the ATCC as a colon adenocarcinoma line established from a 78 year old female, DNA fingerprinting has shown this line to be a derivative of HT-29 (ATCC HTB-38).

The cells are negative for Colon Antigen 3 expression.

The cells are positive for keratin by immunoperoxidase staining.

The cells expressed p53 antigen (the p53 produced has a G -> A mutation resulting in Arg -> His at position 273).

Growth of WiDr cells is inhibited by tumor necrosis factor alpha (TNF alpha).

Inhibitors of dihydrofolate reductase are highly cytotoxic to WiDr cells.

Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. 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: Subcultivation Ratio: A subcultivation ratio of 1:6 to 1:12 is recommended

Medium Renewal: Twice per week

Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.

Add fresh culture medium, aspirate and dispense into new culture flasks.

Preservation: culture medium 95%; DMSO, 5%

Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003

recommended serum:ATCC 30-2020

derivative:ATCC HTB-38
