Abstract

The invention provides a kit for detecting serum amyloid protein and application thereof. The kit comprises a reagent R1 and a reagent R2, wherein the reagent R1 is prepared from a buffer solution, inorganic salt, a surfactant, a preservative, a stabilizer and interference elimination protein; the reagent R2 is prepared from the buffer solution, the inorganic salt, the surfactant, the preservative, the stabilizer and a polystyrene latex particle mixture; the polystyrene latex particle mixture is cross-linked with an SAA (Serum Amyloid A) antibody; the polystyrene latex particle mixture is a mixture of large-diameter polystyrene latex particles and small-diameter polystyrene latex particles. The kit disclosed by the invention is based on PETIA (Particle-enhanced Turbidimetric Immunoassay) and can be generally used for analysis of all kinds of full-automatic biochemical analyzer; during use, the required determining time is short, the specificity is high, the precision degree is high, and the accuracy degree is high.

Description

technical field [0001] The invention belongs to the field of immunodiagnosis, and in particular relates to a kit for detecting serum amyloid and its application. Background technique [0002] Serum amyloid A (Serum amyloid A, SAA) is an acute phase response protein, which belongs to the heterogeneous protein in the apolipoprotein family, with a relative molecular mass of about 12,000. In the acute phase reaction, stimulated by interleukin (Interleukin, IL) and tumor necrosis factor (Tumor necrosis factors, TNF), SAA is synthesized in the liver by activated macrophages and fibroblasts, which can increase to 100 to 1000 times the initial concentration. Similar to C-reactive protein (CRP), SAA is a sensitive indicator reflecting the early inflammation of infectious diseases, which is helpful for diagnosing inflammation, evaluating its activity, monitoring its activity and treatment. [0003] At present, many methods have been applied to the detection of serum SAA, including r...
