Sialic Acid Content Assay kit

Sialic acid (SA), also known as N-acetylneuraminic acid, is an important component ofglycoproteins and glycolipids on the cell membrane. It widely exists in organisms and participatesin various physiological functions on the cell surface. Sialic acid forms a purplish red complex with 5-methylresorcinol in the presence of oxidant. Ithas a maximum absorption peak at 560nm. The content of sialic acid can be calculatedbymeasuring the light absorption value of the product at 560nm
