FITC-dextran is used extensively in microcirculation and cell permeability research utilizing microfluorimetry. FITC-dextran has been used to study plant cell wall porosity and capillary permeability. Plasma proteins have been shown not to bind to FITC-dextran.
FITC-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
Fluorescein isothiocyanate–dextran (FITC-Dextran 4) is use as a fluorescent probe to study cell permeability. FITC-Dextran 4 is used with to study permeability of epithelial cell such as intestinal and renal cells in vivo.
Dextran labeled with fluorescein isothiocyanate for possible use in perfusion studies in animals.

Influenza B virus (IBV) is an acute, respiratory RNA virus that has been assumed to induce the eventual death of all infected cells. We and others have shown however, that infection with apparently cytopathic viruses does not necessarily lead to...

Migration of renal epithelial cells increases after renal tubular damage, but its mechanism has not been clarified in detail. Hyperosmotic stress increased a cellular injury concomitant with a decrease in mRNA and protein expression of claudin-2 in renal tubular epithelial...

During chronic infections and in microbiota, bacteria predominantly colonize their hosts as multicellular structures called biofilms. A common assumption is that biofilms exclusively interact with their hosts biochemically. However, the contributions of mechanics, while being central to the process of...

Clostridium difficile (C. difficile) incidence has tripled over the past 15 years and is attributed to the emergence of hypervirulent strains. While it is clear that C. difficile toxins cause damaging colonic inflammation, the immune mechanisms protecting from tissue damage...
