Abstract

The invention provides a sialic acid assay kit, comprising a reagent R1 and a reagent R2, wherein the reagent R1 is prepared from the following components with corresponding concentrations: 8-20g / L tris(hydroxymethyl) aminomethane, 5-15ml / L HCL, 0.5-5KU / L neuraminidase, 0.5-5KU / L lactate dehydrogenase and 0.1-2mmol / L NADH; the reagent R2 is prepared from the following components with correspondingconcentrations: 8-20g / L tris(hydroxymethyl) aminomethane, 5-15ml / L HCL, 0.5-5KU / L N-acetylneuraminic acid aldolase, 25-100g / L sucrose and 0.6-1.2 ml / L triethanolamine. The invention belongs to the technical field of biological detection. The sialic acid assay kit provided by the invention significantly enhances the anti-interference ability while improving the stability, can significantly reducethe interference of bilirubin, hemoglobin, triglyceride and the like, and is good in accuracy when being used for the determination of sialic acid.

Description

technical field [0001] The invention belongs to the technical field of biological detection, and in particular relates to a sialic acid determination kit and a determination method thereof. Background technique [0002] Sialic acid (Sialic acid, SA), also known as N-acetylneuraminic acid, is one of a variety of natural neuraminic acid derivatives. Its parent structure is an endocyclic amino acid composed of nine carbon atoms. It is a general term for a family of compounds. Sialic acid is an important part of cell membrane glycoprotein, widely distributed in animals, sialic acid in human serum includes free sialic acid and bound sialic acid, the content of free sialic acid is low, bound sialic acid bound to lipoprotein and glycoprotein Acid is the main form of sialic acid in serum. [0003] Sialic acid is related to many biological functions of organisms, and is closely related to cell malignant transformation, cancer metastasis, invasion, loss of contact inhibition, decreas...
