| 商品货号： | TS211000 |
| Organism： | Rattus norvegicus, rat |
| Tissue： | lung |
| Cell Type： | alveolar type II; SV40 transfected |
| Product Format： | frozen |

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. |
| Age： | 56 day old |
| Gender： | male |
| Strain： | Fischer 344 (F344) |
| Storage Conditions： | liquid nitrogen vapor phase |
| Karyotype： | Cells are reported to remain near diploid and karyotypically stable from passage 19-70 with 50% or more of the cells containing 42 chromosomes. At passage 37, there was a translocation between chromosome 1 and 15 which results in trisomy of the q arm of chromosome 1. |
| Derivation： | The RLE-6TN (rat lung epithelial-T-antigen negative) cell line was derived from alveolar Type II cells isolated from a 56 day old male F344 rat using airway perfusion with a pronase solution.xa0Expression of the SV40-T antigen was negative by nuclear immunostaining and by PCR, indicating these cells were derived by a spontaneous immortalization. |
| Clinical Data： | male The RLE-6TN (rat lung epithelial-T-antigen negative) cell line was derived from alveolar Type II cells isolated from a 56 day old male F344 rat using airway perfusion with a pronase solution. |
| Genes Expressed： | cytokeratin 8 and 19 |
| Cellular Products： | cytokeratin 8 and 19 |
| Tumorigenic： | No |
| Effects： | No, not tumorigenic in nude mice |
| Comments： | The cell line exhibits characteristics of alveolar Type II cells such as lipid-containing inclusion bodies (phosphine 3R staining and electron microscopy) and expression of cytokeratin 8 and 19; the cells do not express alkaline phosphatase activity. Expression of several chemotactic cytokines by RLE-6TN cells was reported to be similar to that of primary cultures of alveolar Type II cells. Although these cells appear negative for the SV40 antigen, they should be handled as potentially biohazardous material under at least Biosafety Level 2 containment.
