Sialic Acid (SA) Colorimetric Assay Kit, 50Assays

Sialic acid forms a purplish red complex with methyl resorcinol in the presence of oxidant. And the absorbance conforms to Lambert-Beer's law. The content of sialic acid can be calculated by measuring the OD value at 560 nm. When detect tissue and cell samples, the protein concentration of the sample needs to be detected in addition (E-BC-K165, E-BC-K168, E-BC-K318 are recommended).
