A fluorescence immune assay designed to measure anti-nucleotide antibody activity is described based on the synthesis of a fluorescent nucleotide probe possessing a low fluorescence quantum yield when free in aqueous solution (neutral pH). The fluorophore, AmNS (1-naphthylamine-5-sulfonic acid), was

HPLC-DAD, HPLC-MS/MS, GC-MS and spectrophotometric methods are employed to investigate the degradation process of sodium 1-amino-5-naphthalene sulfonate (1A5NS) aqueous solutions, when exposed to sunlight and UV-lamp (254 nm) irradiations. Experimental results show that both sunlight and 254 nm UV-lamp irradiations
