| 商品货号： | TS212193 |
| Organism： | Mus musculus, mouse |
| Tissue： | embryo |
| Cell Type： | embryonic stem cell , blastocyst derived |
| Product Format： | frozen |
| Morphology： | spherical |
| 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. |
| Age： | embryo, blastocyst embryo, blastocyst |
| Strain： | 129/Ola |
| Applications： | This cell line is a suitable transfection host.xa0 They may also be of use in studies of early post implantation structures. |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | This is a derivative of one of several embryonal stem cell (ES) lines developed by M. Hooper in 1987. |
| Comments： | The cells are deficient in HGPRT (HPRT) and are resistant to 0.06 mM 6-thioguanine.
The cells remain undifferentiated when cultured on feeder layers (embryonic fibroblasts or STO cells).
The cells spontaneously differentiate and form embryonal structures in the absence of a feeder layer.
When injected into blastocysts, the cells can colonize the germline.
After conventional molecular gene modification techniques, they may be used to reconstitute mouse embryos.
|
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated Dulbeccos Modified Eagles Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: 2-mercaptoethanol to a final concentration of 0.1 mM ; fetal bovine serum to a final concentration of 10%.
|
| Subculturing： | Remove medium, add fresh 0.25% trypsin, 0.53mM EDTA solution. Allow the trypsin to loosen the cells, add fresh medium, aspirate and dispense into new flasks containing pre-plated mitomycin-C treated feeder cells (ATCC 56-X.2).
Subcultivation Ratio: A subcultivation ratio of 1:5 is recommended
Medium Renewal: Every 2 to 3 days |
| Cryopreservation： | Freeze medium: Complete growth medium, 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions： | Temperature: 37°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5% |
