购买须知
| 产品名称： | vEPT |
|---|---|
| 商品货号： | TS210694 |
| Organism： | Oryctolagus cuniculus, rabbit |
| Tissue： | kidney; proximal tubule |
| Cell Type： | Epithelial,fibroblast |
| Product Format： | frozen |
| Morphology： | epithelial |
| Culture Properties： | adherent |
| Biosafety Level： | 1
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： | normal |
| Age： | 2 kg |
| Gender： | male |
| Applications： | Currently bovine collagen type I is used as a matrix. However, SV40 T antigen expression was not essential for immortalization, since neither SV40 T antigen nor G418 resistance was detected in the vEPT cell line. They retain electrolyte transport characteristics of the proximal tubule and receptor and signaling mechanisms for angiotensin II. They express cytokeratins 8, 10+11, and 19. The vEPT cell line was derived in 1989 from primary cultures of proximal tubules (S1 segment) microdissected from superficial slices of cortex from the kidney of a normal 2-kg male New Zealand rabbit by M. Romero and U. Hopfer. |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | The vEPT cell line was derived in 1989 from primary cultures of proximal tubules (S1 segment) microdissected from superficial slices of cortex from the kidney of a normal 2-kg male New Zealand rabbit by M. Romero and U. Hopfer. The cells were originally grown on porous inorganic filters coated with poly-L-lysine. Currently bovine collagen type I is used as a matrix. After several passages the cells were co-cultured with irradiated fibroblasts producing a recombinant retrovirus encoding SV40 large T antigen and G418 resistance. However, SV40 T antigen expression was not essential for immortalization, since neither SV40 T antigen nor G418 resistance was detected in the vEPT cell line. These cells display properties of epithelial cells, forming confluent monolayers with apical microvilli, tight junctions, and convolutions of the basolateral plasma membrane. They retain electrolyte transport characteristics of the proximal tubule and receptor and signaling mechanisms for angiotensin II. They express cytokeratins 8, 10+11, and 19. |
