Fluorescein isothiocyanate–dextran (FITC-Dextran 150) is use as a fluorescent probe to study cell permeability. FITC-Dextran 150 is useful to study processes that affect the permeability of the blood brain barrier (BBB) and microvascular structures. FITC-Dextran 150 is used in fluorescence microlymphography.
Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.

Fluorescein-labeled dextran MW 150K (FITC-Dx 150) is commonly utilized as a macromolecular fluorochrome in inflammatory studies. We examined the influence of FITC-Dx 150 on leukocyte activity as assessed by adherence to cheek pouch microvessels. Transcapillary exchange was evaluated as fluorochrome...

Vascular endothelial growth factor (VEGF) induces mild vasodilation and strong increases in microvascular permeability. Using intravital microscopy and digital integrated optical intensity image analysis, we tested, in the hamster cheek pouch microcirculation, the hypothesis that differential signaling pathways in arterioles...
