Thermo Fisher Scientific Offers Primogenix Murine Embryonic Stem Cell Lines

LOGAN, Utah, (January 7, 2008) – Thermo Fisher Scientific Inc., the world leader in serving science, is now offering Primogenix Murine Embryonic Stem Cells for biomedical research. These include the Primogenix B6N and 129/X1 mouse ES cell lines, which allow scientists to develop genetically engineered mice. These have become vital tools in understanding gene function and to model human diseases.

The application of murine stem cells has had such a significant impact on biomedical research that the three scientists who developed the principles for precisely modifying the mouse genome won the Nobel Prize in Medicine this year.

Through an agreement with Primogenix in October, Thermo Fisher Scientific will market and deliver the stem cell lines to customers worldwide. This offering complements the Thermo Scientific HyClone™ AdvanceSTEM™ line – a range of cell-nutrition products developed specifically for applications in stem-cell research. These include the recently launched AdvanceSTEM™ Serum Replacement as well as the Murine Embyonic Stem Cell Screened Fetal Bovine Serum.
