Introduction: Fluorescein isothiocyanate is a yellow powder. Hygroscopic. It can be combined with various antibody proteins. The combined antibody does not lose the specificity of binding to a certain antigen, and still has strong green fluorescence in alkaline solution. After adding acid, it precipitates and the fluorescence disappears. It is slightly soluble in acetone, ether and Petroleum ether.

Uses: Fluorescein isothiocyanate can bind to various antibody proteins, and the combined antibody does not lose its specificity for binding to a certain antigen, and has strong yellow-green fluorescence in alkaline solution. The corresponding antigens can be qualitatively, localized or quantitatively detected by observation under a fluorescence microscope or analysis by flow cytometry. It is used in medicine, agronomy and animal husbandry to quickly diagnose diseases caused by bacteria, viruses and parasites.

Application: Protein fluorescent labeling reagent. For rapid identification of pathogens with fluorescent antibody technology. Dyes and Metabolites.

Uses: Biochemical research. Fluorescent antibody tracing. Rapid diagnosis of diseases caused by viruses and parasites.

Biological activity: FITC (Fluorescein 5-isothiocyanate) is a fluorescent probe for amine labeling. FITC is a pH and Cu2+ sensitive fluorescent dye.
