TRITC-labeled dextran is used in cardiovascular, microcirculation, perfusion, cell monolayer and cell membrane permeability research as fluorescent flux tracer compound that supports the measurement of processes such as blood flow, membrane damage, vascular drainage and renal elimination. It is also used in microcirculation and cell permeability research utilizing microfluorimetry, and possible in perfusion studies in animals. TRITC-dextran has also been used to study plant cell wall porosity and capillary permeability. Plasma proteins have been shown not to bind to TRITC-dextran. Small TRITC-dextrans are often used to measure processes such as endocytosis and cell junction permeability. Rhodamine-dextran, 20 kDa, may be used to study cell processes (such as endocytosis and osmoporation), endothelial or epithelial monolayer porosity, apical-basolateral movements within cell layers and cell junction permeability and drug release from structures such as hydrogens and collagen minirods.
