Description

Eosine-5-isothiocyanate is a fluorescent probe that has affinity for the interstitium of the kidney. This compound inhibits the transport of organic compounds across the renal tubular epithelium, and it is used as a marker for renal function. Eosine-5-isothiocyanate binds to molybdate with high affinity and can be used to measure its concentration in blood plasma. The inhibitory potency of eosine-5-isothiocyanate on carboxylates was tested by perfusing phenolphthalein through a rat's kidneys. Phenoxy dicarboxylates were found to be more potent inhibitors than phenoxy monocarboxylates, but not as potent as eosine-5-isothiocyanate itself. The spectrum of eosine-5-isothiocyanate is in the visible range, so this compound can be detected using
