X-NeuNAc

X-NeuNAc is a chromogenic substrate for neuraminidases, which are enzymes that cleave glycosidic linkages of neuraminic acids. Upon hydrolysis by neuraminidase, halogenated indol-3-ol is released and undergoes rapid aerobic oxidation to the dark blue pigment 5,5'-dibromo-4-4'-dichloroindigo, which can be used to quantify neuraminidase activity.Formal Name: N-acetyl-2-O-(5-bromo-4-chloro-1H-indol-3-yl)-alpha-neuraminic acid, monosodium salt.
