A novel luminescent Tg strain C57BL/6-Tg(CAG-ELuc)1Nkzom (RBRC11951)
|

| The CAG-ELuc mice (RBRC11951) is a transgenic mouse expressing emerald luciferase (ELuc) under the control of the CAG promoter [1]. ELuc is a luciferase cloned from the Brazilian click beetle Pyrearinus termitilluminans luciferase and developed as a bioluminescent imaging probe [2]. ELuc emits green light (λmax = 538 nm) when reacted with D-luciferin, a luminescent substrate. In addition, ELuc has been reported to exhibit brighter signals in mammalian cells compared to conventional Fluc from Photinus pyralis. In vivo and ex vivo imaging analyses of CAG- ELuc mice have shown that ELuc is ubiquitously expressed and has a strong luminescence intensity. The CAG- ELuc mouse line was developed to noninvasively and continuously monitor the early stages of endometriosis lesion formation in endometriosis models. However, CAG- ELuc strain is highly applicable not only to endometriosis models, but also to in vivo imaging systems (IVIS) in a variety of situations. It is expected to be used in a wide range of research areas in the future. |
