Former Common nameB6D2F1-Tg(CAG/su9-DsRed2,Acr3-EGFP), RBGS002Osb (Nov. 2011), RBGS-002
H-2 Haplotype
ES Cell line
Background strainJcl:B6D2F1
Strain developmentDeveloped by Masaru Okabe, Research Institute for Microbial Diseases, Osaka University. This transgenic line was generated by coinjected with Acr3-EGFP and CAG/su9-DsRed2 transgene constructs into fertilized eggs. C57BL/6 and DBA/2 mixed background.
Strain descriptionTrangenic mice expressing GFP in sperm acrosome from acr3-EGFP and RFP in sperm mitochondoria from CAG/su9-DsRed2. The dual fluorescent sperm show normal fertilizing ability and can be observed through uterine and oviductal walls under excitation light. Acrosome reacted sperm and acrosome intact sperm are easily distinguishable from each other by red fluorescence. Acr3-EGFP, in which EGFP with a proacrosin signal peptide and proacrosin N-terminal peptide were connected to the acrosin promoter. CAG/su9-DsRed2, in which a RFP(DsRed2) is connected to the CAG promoter with a mitochondrial import signal sequence of Atp5g1(su9).
