Strain Data Sheet



BRC No.RBRC04217
SpeciesMus musculus
Strain nameC57BL/6N-Tg(CAG-KO,ChR2/mCherry)419-3Sasa/Rbrc
Former Common name
H-2 Haplotype
ES Cell line
Background strainC57BL/6NCrlCrlj
Strain developmentDeveloped by National Institute for Basic Biology and RIKEN BioResource Center in 2010. C57BL/6N background.
Strain descriptionOptogenetic transgenic mice. A transgenic construct containing CAG promoter, a loxP-KO (Kusabira Orange)-STOP-loxP sequence and a ChR2 (channelrhodopsin-2)-mCherry fusion cDNA was microinjected into C57BL/6NCrlCrlj fertilized eggs. Expression of KO and Halo/mCherry has not been examined yet. Users are encouraged to test the expression pattern and feed back the data for the research community.
Colony maintenanceCarrier x Noncarrier [C57BL/6NCrlCrlj]. Hemizygous Tg mice are viable and fertile (viability and fertility of homozygotes are unknown).
