Nano-Glo® Fluorofurimazine In Vivo Substrate (FFz)

Reagent Optimized for in vivo Detection

NanoLuc® luciferase provides a new reporter option for advanced in vivo imaging applications. Its small size is ideal for engineering into compact genomes, and ATP-independence allows in vivo monitoring of both intracellular and extracellular events. Substrate specificity makes NanoLuc® luciferase an ideal complementary reporter to firefly luciferase for an improved dual-luciferase in vivo imaging solution.

The Nano-Glo® Fluorofurimazine In Vivo Substrate (FFz) is an optimized reagent designed specifically for in vivo detection of NanoLuc® luciferase, NanoLuc® fusion proteins or reconstituted NanoBiT® luciferase. This optimized, aqueous-soluble, in vivo detection reagent provides increased substrate bioavailability for bright, stable signals and offers flexible delivery options with handling requirements compatible with in vivo workflows.

Ideal for in vivo analysis of:

Dual-reporter imaging with firefly luciferase
Viral distribution
CAR T-cell tracking

Exosome/extracellular vesicles
Optogenetics
BRET-based reporters for enhanced deep-tissue imaging

Flexible Substrate Delivery

The Nano-Glo® Fluorofurimazine In Vivo Substrate can be delivered via multiple routes of administration. Each method offers different signal intensity and kinetics, allowing flexibility between experimental systems.

NanoLuc® signal of 4T1 primary tumors in BALB/c mice. Cells expressing NanoLuc® luciferase were orthotopically implanted into the #3 mammary fat pad of female BALB/c mice, and tumors were allowed to grow for 22 days. Mice were injected with FFz via i.p. (top image; circles) or i.v. injection (bottom image; squares). Bioluminescence imaging was done at the University of Wisconsin Small Animal Imaging and Radiotherapy Facility.

Ideal for Cell and Gene Therapy Applications

The small size of NanoLuc® luciferase makes it easy to package into viral genomes, allowing you to track tissue penetration of your virus for infectious disease or gene therapy applications.

Mice injected with increasing levels of AAV9-NanoLuc®-HaloTag® viral particles

In vivo whole-body imaging of mice injected with AAV9-NanoLuc®-HaloTag® viral particles. Mice were injected with increasing levels of AAV9-NanoLuc®-HaloTag® viral particles. Nano-Glo® FFz (0.44μmol) was injected 7- and 13-days post-transduction followed by in vivo imaging. Tissue tropism starts to appear at 7 days, and a stronger signal and more extensive tissue tropism is visible after 13 days. Bioluminescence imaging was done at the University of Wisconsin Small Animal Imaging and Radiotherapy Facility.

NanoLuc® reporters can be multiplexed with firefly reporters to enable two-population bioluminescent imaging in animals. This publication used a NanoLuc® reporter to track tumor size and a firefly substrate to visualize CAR-T cells in the same animal over multiple days:
