| Disease： | colorectal adenocarcinoma |
| Gender： | female |
| Applications： | transfection host |
| Images： |  |
| Derivation： | 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). xad |
| Clinical Data： | 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). female |
| Antigen Expression： | HLA A24, A32, B15, B18 |
| Receptor Expression： | epidermal growth factor (EGF) |
| Genes Expressed： | xad carcinoembryonic antigen (CEA) 118 ng/10 exp6 cells/10 days; Colon Specific Antigen (CSAp); transforming growth factor beta; keratin,HLA A24, A32, B15, B18. 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). |
| Cellular Products： | carcinoembryonic antigen (CEA) 118 ng/10 exp6 cells/10 days; Colon Specific Antigen (CSAp); transforming growth factor beta; keratin |
| Tumorigenic： | Yes |
| Effects： | Yes, in nude mice (Tumors developed within 21 days at 100% frequency (5/5) in nude mice inoculated subcutaneously with 10(7) cells) |
| Comments： | 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. |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Eagles 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%.
|
| Subculturing： | Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.xa0Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
Subcultivation Ratio: A subcultivation ratio of 1:10 to 1:20 is recommended
Medium Renewal: Twice per week
|
