Overview
Revvity offers IVISbrite™ D-luciferin for in vitro, in vivo and ex vivo bioluminescent imaging in two formats – lyophilized and injectable. D-luciferin is a substrate for Firefly luciferase (such as Red-FLuc) and can be used in conjunction with our IVISbrite Tumor Cell Lines or cells transfected with our IVISbrite Red F-luc-Puromycin (formerly RediFect™ Red-FLuc) and IVISbrite Red F-luc-GFP (formerly Red-FLuc-GFP) lentiviral particles for in vitro, in vivo or ex vivo imaging.
After the bioluminescent cell line expressing firefly luciferase is established in a mouse or other small animal model, D-luciferin substrate is injected. The substrate is then used by the bioluminescent reporter gene to produce a light signal within the cells, which allows visualization of the cells within the mouse (or other) model. This luminescence can be visualized and measured using an appropriate 2D or 3D imager.

FAQs
Q. How do I know whether to use the intraperitoneal (i.p.) luciferin injection protocol or the intravenous (i.v.) injection protocol, when injecting luciferin for bioluminescence in vivo imaging?
A. Most scientists use i.p injections. Subcutaneous injections are sometimes performed as well. If the signal is weak, you can do an i.v. injection, but you will need to image as soon as you inject (which can be very cumbersome).
