CAS :2-O-(4-Nitrophenyl)-a-D-N-glycolylneuraminic acid is commonly used to measure the activity of sialidase enzymes, specifically those that cleave glycoconjugates containing 2-O-(4-nitrophenyl)-alpha-D-N-glycolylneuraminic acid. The resulting product can be detected by measuring the absorbance at a specific wavelength using a spectrophotometer. This substrate offers a high degree of specificity for glycolylneuraminic acid-containing substrates and is useful for both research and diagnostic purposes.Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :446.36 g/mol
