Protein fluorescent labeling reagent is also a medical diagnostic drug. It is mainly used as a fluorescent dye in fluorescent antibody technology. It can bind to various antibody proteins. After binding, the antibody does not lose the specificity of binding to a certain antigen, and has strong green fluorescence in alkaline solution. It is used in medicine, agronomy and animal husbandry, and can quickly diagnose diseases caused by local bacteria, viruses and parasites. |
production method | 4-nitrophthalic anhydride (see C8H3NO5,[5466-84-2]) and resorcinol react at 195-200 ℃ for 10h, cyclically form a mixture of 3 '-nitro fluorescent yellow and 4'-nitro fluorescent yellow, then acetylated with acetic anhydride and hydrolyzed with saturated sodium hydroxide-ethanol solution to obtain 4 '-nitrofluorescein. Then 4 '-nitrofluorescein is dissolved in ammonia water, rested with nickel and hydrazine hydrate for 2h at room temperature, and reduced to 4'-amino fluorescein. The most elevated acylation, elimination to obtain fluorescein isothiocyanate. |
