Allgemeine Beschreibung
The generation of gene-modified mice, created by homologous recombination in embryonic stem (ES) cells, has become a fundamental tool for analyzing gene function. The influence of genetic background on phenotype has been shown to be an important consideration in selection of a mouse model. Furthermore, the time required to achieve congenic status, which can be 18-24 months has further stimulated demand for targeting in pure inbred strains including C57BL/6 (B6) mice.
Millipore′s B6-White Murine ES cell line is the first commercially available C57BL/6 tyrc-2J albino line that allows for rapid coat-color determination of successful chimerism in the C57BL/6 mouse strain. When B6-White ES cells are injected into C57BL/6 blastocysts, chimeric mice are easily identified by their coat color (a mix of black and white patches), whilst non-chimeric littermates are black. These cells allow for the efficient generation of gene-targeted mice in a pure C57BL/6 genetic background, thus providing more experimental flexibility. Additionally the use of these cells can lower production costs by eliminating the need to maintain an albino blast donor colony, in order to assess chimerism by coat color when targeting in the C57BL/6 strain.
For germline transmission confirmation by coat color, it is recommended that male chimeras are mated with homozygous females of the B6-white strain (strain name: C57BL/6J-Tyrc-2J/J - available from Jackson Labs, stock number 000058).
