|---|---|
| 商品货号： | TS212370 |
| Organism： | Homo sapiens, human |
| Tissue： | HeLa contaminant |
| Product Format： | frozen |
| Morphology： | epithelial |
| Culture Properties： | adherent |
| Biosafety Level： | 2 Cells contain human papilloma virus (HPV-18)
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. |
| 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 normal liver tissue, 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： | The cells produce a C type retrovirus. The cells are positive for keratin by immunoperoxidase staining. |
| Cellular Products： | Keratin |
| Tumorigenic： | Yes |
| Effects： | Yes, in Syrian hamsters |
| Comments： | The cells are positive for keratin by immunoperoxidase staining. |
| Complete Growth Medium： | Minimum essential medium (Eagle) in Earles BSS with non-essential amino acids and 1 mM sodium pyruvate, 90%; fetal bovine serum, 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.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994. |
