| 商品貨號 | B164903 |
| Organism | Homo sapiens, human |
| Tissue | HeLa contaminant |
| Product Format | frozen |
| Morphology | epithelial |
| Culture Properties | adherent |
| Biosafety Level | 2 [Cells contain human papilloma virus]
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Disease | Carcinoma, Papilloma |
| Applications | This cell line is a suitable transfection host. |
| Storage Conditions | liquid nitrogen vapor phase |
| Derivation | This line was originally thought to be derived from an epidermal carcinoma of the mouth, but was subsequently found, based on isoenzyme analysis, HeLa marker chromosomes, and DNA fingerprinting, to have been established via HeLa cell contamination. |
| HeLa Markers | Y |
| Genes Expressed | keratin |
| Comments | The cells are positive for keratin by immunoperoxidase staining.
KB cells have been reported to contain human papillomavirus 18 (HPV-18) sequences.
NOTE: Cells of this line contain HeLa marker chromosomes, and were derived via HeLa contamination |
| 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%.
|
| Subculturing | 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 37°C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:10 is recommended
Medium Renewal: 2 to 3 times per week |
| Cryopreservation | Freeze medium: Complete growth medium, 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature |
| Culture Conditions | Temperature: 37°C |
