Fluorescein Di-β-D-Glucuronide

Fluorescein Di-β-D-Glucuronide is a fluorescent substrate enabling real-time, non-invasive visualization of bacterial β-glucuronidase activity. It is widely used in both in vitro assays and in vivo imaging in animal models, such as nude mice, to study gut microbiota function and evaluate inhibitor pharmacodynamics in conditions like drug-induced enteropathy.
