Abstract

The invention provides a cystatin C latex-enhanced turbidimetry detection kit. The cystatin C latex-enhanced turbidimetry detection kit comprises double liquid components, namely, a reagent R1and a reagent R2, wherein the reagent R1 is prepared from 10 to 100 mM/L buffer solution, 5 to 50g/L stabilizer and 0.1 to 1g/L preservative, wherein purified water is taken as the solvent; the reagent R2 isprepared from 10 to 100mM/L buffer solution, 0.1 to 1 percent surfactant, 5 to 50g/L stabilizer, 0.1 to 1g/L preservative, 1 to 10 percent latex microspheres crosslinking with a recombinant antihumanCys-C single-chain antibody, and 2 to 15 percent of latex microspheres crosslinking with a goat antihuman Cys-C polyclonal antibody, wherein purified water is taken as the solvent. The invention further provides preparation and application methods of the cystatin C latex-enhanced turbidimetry detection kit. By adopting the detection kit, the advantages of a polyclonal antibody detection kit and amonoclonal antibody detection kit are combined, and the specificity and sensitivity of detection can be enhanced simultaneously.

Description

technical field [0001] The invention relates to the fields of genetic engineering technology and immunological determination and analysis, in particular to a cystatin C latex enhanced turbidimetric detection kit and a preparation method thereof. Background technique [0002] Cystatin C (Cystatin C, Cys-C) is one of the members of cysteine ​​protease inhibitor superfamily 2 and is a cysteine ​​protease inhibitor composed of 122 amino acid residues. Products of housekeeping genes that are constantly expressed on nucleated cells. Cys-C in blood is basically filtered by glomerulus, therefore, the content of Cys-C in serum or plasma is completely determined by glomerular filtration rate (Glomeruar filtration rate, GFR). Because it has: ①stable production rate; ②stable blood concentration, not affected by other pathological changes, not combined with protein; ③glomerular free filtration, not reabsorbed or secreted; it is ideal for GFR detection Endogenous markers.
