BRC No.RBRC06449
TypeCRISPR/Cas9 (Transgene)Cartagena
SpeciesMus musculus
Strain nameC57BL/6-H3t<em1Osb>
Former Common nameH3mmT KO, B6-H3mmT EN, H3mmT knockout mouse
H-2 Haplotype
ES Cell line
Background strain
Strain developmentDeveloped by Jun Ueda and Kazuo Yamagata, Research Institute for Microbial Diseases, Osaka University and Kazumitsu Maehara, Akihito Harada and Yasuyuki Ohkawa, Graduate School of Medical Sciences, Kyushu University in 2013. Generated by injecting Cas9 and gRNA (GCAAGGGAGGCGGACGATTCAGG) expression plasmids into the C57BL/6 fertilized eggs. Off-target analysis was not examined.
Strain descriptionSperm specific histone H3 variant, H3mmT gene knockout mice. A 16 bp including ATG was deleted. Homozygous mutant males are infertile.
Colony maintenanceHeterozygote x Wild-type [C57BL/6NCrSlc]
