Genetic information | The Gt(ROSA)26Sor locus is expressed in practically all mouse tissues, in embryos, neonates, adults. Originally discovered by insertion of a gene-trap vector with a lacZ reporter gene (Friedrich and Soriano, 1991). ES cells and blastocysts derived from this line (commonly called ROSA26-lacZ) have been used in innumerable developmental studies, to mark and follow specific lineages of cells. A cre recombinase reporter line called R26R was published in 1999, taking advantage of the ubiquitous expression of the Gt(ROSA)26Sor locus (Soriano et al., 1999). The lacZ reporter gene is not expressed unless the cell also expresses (or has expressed in the past) the cre recombinase protein. This line has been used in many publications, to determine where cre is active in cre-expressing transgenic mice. This variant of the R26R reporter mice has been engineered, where, instead of lacZ, EYFP (enhanced yellow fluorescent protein) is expressed as the reporter gene (Srinivas et al., 2001). |
