Abstract

The invention relates to the technical field of medicine and biochemistry and particularly relates to a kit for determining rheumatoid factors, aiming at solving the problems in the prior art that a rheumatoid factor detection process is complicated to operate and the determination accuracy is low. Aiming at solving the technical problems above, the technical scheme provided by the invention is as follows: a kit for determining hyaluronic acid is provided, wherein the kit is composed of double liquid reagents R1 and R2, the reagent R1 is prepared from the following components: 30mmol / L-230mmol / L of a Tris buffering solution, 2.0mL / L-6.0mL / L of Tween-80, 5g / L-15g / L of polyethylene glycol-8000, 30mmol / L-50mmol / L of EDTA (Ethylene Diamine Tetraacetic Acid), 0.4g / L-1.0g / L of sodium azide and a solvent which is a purified water; the reagent R2 is prepared from the following components: 50mmol / L-150mmol / L of a Tris buffering solution, 5mmol / L-25mmol / L of glycerol, 0.4g / L-1.0g / L of sodium azide, 20g / L-60g / L of bovine serum albumin, 0.5%-4.0% of an emulsion-coated anti-human rheumatoid factor antibody and a solvent which is purified water. The kit for determining the rheumatoid factors has the advantages of high accuracy, convenience for operation and the like.

Description

technical field [0001] The invention relates to the technical fields of medicine and biochemistry, in particular to a kit for measuring rheumatoid factor. Background technique [0002] Rheumatoid factor (rheumatoid factor, RF) can be divided into five types: IgM, IgA, IgG, IgD, and IgE. It is a type of autoantibody against the antigenic epitope on the Fc fragment of IgG in rheumatoid arthritis serum. Patients with rheumatoid factor positive More associated with extra-articular manifestations, such as subcutaneous nodules and vasculitis. The positive rate of IgM type RF was 60%-78%. [0003] Rheumatoid factor (RF) is found in the serum of patients with rheumatoid arthritis (RA). It is an autoantibody that targets denatured IgG. It mainly exists in the serum and joint fluid of patients with rheumatoid arthritis. It is an anti-denatured IgG antibody, which is of the IgM type. Can bind to IgG Fc fragment. RA patients and about 50% of healthy people have RF-producing B cell c...
