Short Description

Animal model for PERIOD2 protein expression reporting

#researchtool #animalmodel


Circadian rhythms are a popular area of research, and a number of proteins involved in the process have already been identified – including the PERIOD2 protein. Northwestern investigators have developed a mouse strain expressing a luciferase reporter gene fused to the C-terminus of the mouse Period 2 (Per2) gene to create a PER2::LUCIFERASE fusion protein. This fusion gene replaces the endogenous Per2 gene and enables scientists to follow the level of the PERIOD2 protein by performing luciferase assays. The protein can be followed in vivo in mice, from tissues taken from mice and explanted in culture, and from cells prepared from mouse tissues, such as mouse embryonic fibroblasts (MEFs) and skin fibroblasts. Circadian rhythms can subsequently be measured from mice, tissue explants, or cells using bioluminescent recordings or imaging.
