B6.129P2-Gt(ROSA)26Sortm1(CAG-Brainbow2.1)Cle/J
Cat. No.: CEMM-07250340
Common Name: R26R-Confetti; R26R-Brainbow2.1; Rosa26-CAG-Brainbow2.1/Confetti
The R26R-Confetti conditional allele has a CAG promoter followed by a floxed-STOP cassette and the Brainbow 2.1 construct all targeted into the Gt(ROSA)26Sor locus. The R26R-Confetti allele functions as a stochastic multicolor Cre recombinase reporter of multiple fluorescent proteins from a single genomic locus. These R26R-Confetti mice allow a way to label and distinguish individual / adjacent cells with nuclear localized, membrane-targeted, or cytoplasmic fluorescent proteins in cre recombined cells.

| Molecular Note |
A targeting vector containing (from 5' to 3') a strong CAGG promoter, a loxP site, a PGK-Neo-pA cassette (serving as a transcriptional roadblock), and the Brainbow 2.1 construct. This entire construct was inserted between exons 1 and 2 of the Gt(ROSA)26Sor locus. The Brainbow 2.1 construct was designed with four fluorescent protein sequences uniquely positioned in a tandem fashion and delimited by loxP sites in opposite orientation. Specifically, this Brainbow 2.1 coding region is composed of two adjacent floxed head-to-tail tandem dimers. The first head-to-tail dimer contains a loxP site and humanized Renilla GFP (hrGFPII; with nuclear localization signal plus polyA sequence) in forward orientation and a loxP site and monomeric EYFP (mYFPA206K plus polyA sequence) in reverse orientation. The second head-to-tail dimer contains a loxP site and tdimer2 RFP plus polyA sequence in forward orientation, and a loxP site and mCerulean CFP (with membrane tethering palmitoylation sequence plus polyA sequence) in reverse orientation. A single FRT site is located at the 3' end of the Brainbow 2.1 construct.

| Breeding Considerations |
Both heterozygous and homozygous mice are viable and fertile. When maintaining a live colony, heterozygous mice may be bred together, to wildtype mice from the colony or to C57BL/6J inbred mice. Alternatively, homozygous mice may be bred together.
