These Thy1-Brainbow 2.1 (line R) transgenic mice are viable and fertile. The mice possess two invertible DNA segments (four fluorescent protein sequences in total) uniquely positioned in tandem and flanked with LoxP sites to generate a larger number of recombination outcomes; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Although the fluorescent protein immediately adjacent to the promoter, hrGFPII (with nuclear localization signal), was designed to be expressed prior to Cre-mediated recombination, basal hrGFPII expression may not be observed in mouse tissues. When bred to Cre recombinase expressing mice, however, the resulting offspring can have one of three different inversions for each transgene in each cell of the cre expressing tissue(s). In addition, two excision events may reduce the construct to one of two single invertible DNA segments which can continue to invert as long as cre is present. These different recombination possibilities can be used to express four genes (hrGFPII, mYFP, tdimer2(12) (RFP), or mCerulean (CFP)) to the peripheral and central neurons. A nuclear localization signal targets the hrGFPII to the nucleus, a palmitoylation sequence tethers the mCerulean (CFP) to the membrane (allowing clear labeling of axonal processes), and cytoplasmic tdimer2(12) (RFP) and mYFP better labeled neuronal cell bodies and dendrites. Integration of tandem transgene copies yields combinatorial fluorescent protein expression in each cell, and thus many possible cell colors, providing a way to distinguish adjacent neurons and visualize other cellular interactions. Of note, the single FRT site inserted at the 5' end of the transgene allows tandem transgene copy number reduction through Flp-mediated recombination if desired. These Brainbow 2.1 (founder line R) mice allow labeling of individual neurons and glia in peripheral and central neurons with nuclear localized, membrane-targeted, or cytoplasmic fluorescent proteins in cre recombined cells, and may also be useful in conjunction with other Brainbow strains (Stock No. 007901, Stock No. 007910, Stock No. 007911) for neurobiological studies.Strain Development
The Thy1-Brainbow 2.1 transgene was designed with the mouse Thy1 regulatory elements surrounding four fluorescent proteins (green (GFP), enhanced yellow (EYFP), red (RFP), and cyan (CFP)) 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 head to tail tandem dimers, the first contains a loxP site, humanized Renilla GFP (hrGFPII (Stratagene); with nuclear localization signal), and polyA sequence in forward orientation, and a LoxP site, monomeric EYFP (mYFPA206K), and polyA sequence in reverse orientation. The second head to tail dimer contains a LoxP site, tdimer2(12) RFP, and polyA sequence in forward orientation, and a LoxP site, mCerulean CFP (with membrane tethering palmitoylation sequence), and polyA sequence in reverse orientation. A single FRT site is located at the 3' end of the coding region. This transgene was microinjected into C57BL/6JxCBA hybrid oocytes. Founder mice (line R) were bred with C57BL/6. The resulting mutant mice were backcrossed to C57BL/6 for at least 5 generations prior to arrival at The Jackson Laboratory. Upon arrival, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.The hrGFPII variant of GFP (from Stratagene vector phrGFPII-C) has amino acid substitutions designed to improve spectral properties and performance in mammalian systems. The monomeric EYFP (mYFPA206K) has an amino acid substitution replacing a hydrophobic region with a positively charged residue designed to prevent dimerization. The tdimer2(12) RFP is a non-oligomerizing DsRed variant with a 12 residue linker fusing two copies of the protein (tandem dimer). The monomeric Cerulean (mCerulean) is a variant of ECFP (ECFPS72A/Y145A/H148D/A206K) with amino acid substitutions designed to improve spectral properties and prevent dimerization.

| Strain of Origin | C57BL/6J x CBA | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||
| Expressed Gene | YFP, Yellow Fluorescent Protein, jellyfish | ||
| Yellow Fluorescent Protein (YFP) is a derivative of Green Fluorescent Protein (GFP), a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance fluorescence intensity and shift the wavelength emitted when excited. When YFP is utilized in a transgenic construct, tissue expressing sufficient amounts of YFP will fluoresce yellowish-green when exposed to a 513 nm light source. | |||
| Expressed Gene | RFP, Red Fluorescent Protein, jelly fish | ||
| Red Fluorescent Protein (RFP), derived from marine invertebrate organisms such as the soft coral Discosoma spp and reef coral, Heteractis crispa, is a versatile reporter molecule which has found use in many biological applications. The wild type protein, which is an obligate tetramer, is not well tolerated in mammalian systems. The original molecule has been modified in order to optimize expression to mammalian physiology (examples include monomeric RFP, mRFP1, DsRed, etc). | |||
| Expressed Gene | CFP, Cyan Fluorescent Protein, jellyfish | ||
| Cyan Fluorescent Protein (CFP) is a derivative of Green Fluorescent Protein (GFP), a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance fluorescence intensity and shift the wavelength emitted when excited. When CFP is utilized in a transgenic construct, tissue expressing sufficient amounts of CFP will fluoresce cyan when exposed to a 433 nm light source. | |||

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.Ordering and Purchasing Information
