TypeTransgene CongenicCartagena
SpeciesMus musculus
Strain nameB6.Cg-Tg(FucciG1)#596Bsi
Former Common nameB6.Cg-Tg(Fucci)596Bsi, Fucci G1-red#596, B6;B6D2-Tg(Fucci)596Bsi
H-2 Haplotype
ES Cell line
Background strainC57BL/6N and DBA/2N mixed
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Asako Sakaue-Sawano and Atsushi Miyawaki, RIKEN Brain Science Institute. The transgene was injected into the pronuclei of B6D2F1 fertilized eggs. The mice were backcrossed to C57BL/6N.
Strain descriptionTransgenic mouse strains express fucci (fluorescent, ubiquitination-based cell cycle indicator) under the control of CAG promoter. These mice can be used to clearly visualize the cell cycle with fluorescence, i.e. S/G2/M phase nuclei green and those in G1 phase red in vivo. #474 (RBRC02704), #492 (RBRC02705), #504 (RBRC02706): Fucci-S/G2/M-Green (mAG-hGeminin(1/110)). #596 (RBRC02707), #610 (RBRC02708), #639 (RBRC02709): Fucci-G1-Red (mKO2-hCdt1(30/120)). For whole body (various tissues): #504 and #596 (Cell 2008). For hematopoietic system (monocyte and macrophage): #474 and #610 (Development 2013). For lymphocytic system: #492 and 639 (PNAS 2010). #474 and #610 double transgenic mice (RBRC02817). #504 and #596 double transgenic mice (RBRC02892). Whole-body visualization of Fucci mice with a flashlight (PCR genotyping is also available.): Check the Fucci S/2G/M-Green expressing mice at 1-4 days after birth by using blue LED flashlight through a sharp-cut filter in the dark box. Check the Fucci G1-Red expressing mice within 1-4 days after birth by using green LED flashlight through a green band-cut filter in the dark box. The part with few hairs such as in the mouth and auricles is suitable for the observation of fluorescence. Visualizing device: blue LED flashlight (470 nm), S470/30 filter, 535AF26 filter, sharp-cut filter (500 or 520 nm), green band-cut filter (red filter). #474 and #504: Tg homozygous mice are viable and fertile. #596: Tg homozygous mice are probably lethal (details unknown). #492, #610 and #639: Viability and fertility of homozygous mice are unknown (probably decreased fertility, details unknown).
