Irradiated Gibco C57BL/6 Mouse Embryonic Fibroblasts (MEFs) are feeder cells that support the culture of healthy undifferentiated embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), especially mouse ESCs/iPSCs. Manufactured by MTI-GlobalStem and equivalent to MTI-GlobalStem Cat. Nos. GSC-6002G and GSC-6202G, these MEF cells are isolated from inbred C57BL/6 mice, mitotically arrested by irradiation, and tested to help ensure performance and minimize the risk of contamination.

• Help save precious time with pre-inactivated, ready-to-use MEFs
• Culture ESCs and iPSCs with confidence using meticulously tested feeder cells
• Provide optimum support for mouse ESCs and iPSCs

Help save time with ready-to-use MEFs
Irradiated C57BL/6 MEFs help save time and trouble dealing with an animal facility, performing tedious, time-consuming dissections, and expanding and testing cells day after day, week after week. Focus on your research with these pre-inactivated, ready-to-use feeders.

Culture with meticulously tested feeder cells
Each lot of irradiated C57BL/6 MEFs is tested for bacteria, fungi, mycoplasma, and mouse pathogens to minimize the risk of contamination. Each lot is also tested for post-thaw viability (typically greater than 95%) and ability to support mouse and human ESCs to help ensure robust and consistent performance. Culture your ESCs and iPSCs with confidence, knowing that you can rely on these high quality feeder cells.

Provide optimum support for mouse ESCs and iPSCs
While C57BL/6 MEFs can also support human ESCs and iPSCs, these feeder cells work particularly well for culturing mouse ESCs and iPSCs, showing better results compared to CF1 and ICR strain MEFs.
