购买须知
| 产品名称： | HELA |
|---|---|
| 商品货号： | TS258870 |
| <strong>Cell line </strong>： | HELA |
| DSMZ no. ： | TS258870 |
| Species ： | originally confirmed as human with IEF of G6PD, MDH, NP |
| Cell type ： | cervix carcinoma |
| Origin ： | established from the epitheloid cervix carcinoma of a 31-year-old black woman in 1951; later diagnosis changed to adenocarcinoma; first aneuploid, continuously cultured human cell line |
| Reference(s) ： | 14926, 14555, 18012, 18013 |
| Biosafety level ： | 1 |
| Risk assessment ： | The cell line is infected with papilloma virus type 18 (HPV-18). The cells contain several copies as proviruses integrated into the eukaryotic genome. The integrated virus genomes are incomplete and exhibit 2-3 kb deletions of the E2-L2 region. An activation and transmission of the HPV-18 during handling of the cell line is improbable. The cell line is categorized biosafety level 1. |
