This enzymatic method for determination of sialic acid involves use of neuraminidase (EC 3.2.1.18), N-acetylneuraminate lyase (EC 4.1.3.3), acylglucosamine 2-epimerase (EC 5.1.3.8), N-acetylhexosamine oxidase (from Pseudomonas sp.), and peroxidase (EC 1.11.1.7). Because the method does not require pyruvic acid in
