Eosin 5-isothiocyanate (EITC) is a fluorescence probe. EITC tagged molecules may be used together with fluorescein-5′-isothiocyanate (FITC) tagged molecules in fluoresce resonance energy transfer (FRET) based assays.

Quantitative evaluation of minimal polynucleotide concentrations has become a critical analysis among a myriad of applications found in molecular diagnostic technology. Development of high-throughput, nonenzymatic assays that are sensitive, quantitative and yet feasible for point-of-care testing are thus beneficial for

The characteristics of the anion transport system in human erythrocyte, which can be modified by eosin 5-isothiocyanate (EITC), were studied using the pH titration method and by measuring the sulfate efflux. Based on the pH dependence of EITC binding to

Self-association of bovine serum albumin (BSA) was explored using fluorescence resonance energy transfer (FRET) between two populations of the protein labeled separately with either fluorescein-5'-isothiocyanate (FITC) or eosin-5'-isothiocyanate (EITC). The energy transfer reached the steady state after 5 s at

Although eosin-5-maleimide (EM) covalently labels band 3 and has been thought to react at the external-facing anion transport site, EM reversibly inhibits Cl- exchange at 0 degrees C in a noncompetitive fashion, indicating that under these conditions it does not
Ca2+-ATPase molecules were labeled in intact sarcoplasmic reticulum (SR) vesicles, sequentially with a donor fluorophore, fluorescein-5'-isothiocyanate (FITC), and with an acceptor fluorophore, eosin-5'-isothiocyanate (EITC), each at a mole ratio of 0.25-0.5 mol/mol of ATPase. The resonance energy transfer was determined
