Abstract

A hepatitis c virus antigen-antibody joint detection reagent box is characterized by comprising a calibrator(1), a double-marker enzyme conjugate (2), a negative and positive contrast (3), light-emitting liquid (4) and a micropore coated plate (5), wherein the light-emitting liquid contains light-emitting liquid 1 and light-emitting liquid 2, the light-emitting liquid 1 contains luminal 0.7 g / L, cinnamic acid 0.9 g / L, 4-iodophenylboronic acid 0.2 g / L, iodobiphenol 0.25 g / L, dimethylformamide 25 ml / L, polyving akohol 5 g / L, polyvinylpyrrolidone 8 g / L, polyethylene glycol 600 3 g / L, ethylenediamine tetraacetic acid 4 g / L, gentamicin sulfate 1600 thousands / L, urea peroxide 0.4 g / L, and pH 9.0 Tris buffer solution 0.1 mol / L. The light-emitting liquid 2 contains acridinium ester derivative 0.1 mg / ml, polyethylene glycol 600 3 g / L and 0.1 mol / L of pH 9.0 Tris buffer solution containing 0.1% of TWEEN-20. The invention further discloses a preparation method and a using method of the reagent box. The hepatitis c virus antigen-antibody joint detection reagent box has the advantages of being quick in reaction and low in cost.

Description

technical field [0001] The invention relates to the field of immunoanalysis medicine, specifically, the invention provides a hepatitis C virus (HCV) antigen-antibody combined detection kit and a preparation method thereof. Background technique [0002] Hepatitis C virus (Hepatitis C virus, HCV) is a class of single-strand positive-strand RNA virus, which has an envelope, a thorn-like protrusion structure on the surface, and large variations in virus particles. Blood transfusion and injection are the important transmission routes of HCV in my country. The development of hepatitis C is hidden, the clinical manifestations are not typical, and the clinical diagnosis and curative effect observation depend on the laboratory test results. [0003] The hepatitis C virus genome contains an open reading frame (ORF), which can encode a viral precursor polypeptide of amino acid residues, which respectively constitute the core protein (c), matrix protein (M), coat protein (E) and Anothe...
