Abstract

The invention discloses a lipoprotein (a) determination kit and a preparation method thereof. The kit comprises a reagent R1 and a reagent R2 which are liquid components and are mutually independent, the reagent R1 comprises a buffer solution, a stabilizer, an accelerator, an antiseptic, an anti-human rheumatoid factor antibody and purified water used as a solvent, and the reagent R2 comprises the buffer solution, a surfactant, the stabilizer, a suspending aid, the antiseptic, a latex coated anti-human lipoprotein (a) antibody and purified water used as a solvent. The preparation method comprises the following steps: preparing the reagents according to the component content; mixing a sample to be determined with the reagent R1 and the reagent R2 to fully react the sample to be determined with the reagent R1 and the reagent R2; determining the absorbance difference by using a fully-automatic biochemical analyzer after the reaction; and calculating the concentration of lipoprotein (a) in the sample according to the absorbance change value. The kit has high accuracy.

Description

technical field [0001] The invention relates to the technical fields of medicine and biochemistry, in particular to a kit for measuring lipoprotein (a) and a preparation method thereof. Background technique [0002] Lipoprotein (a) is a special independent plasma lipoprotein, which was discovered by Norwegian geneticist Berg in 1963 when he was studying the genetic variation of low-density lipoprotein. In the late 1980s, it was discovered that lipoprotein (a) was associated with atherosclerosis. [0003] Lipoprotein (a) is a lipoprotein rich in cholesterol. The core part is neutral lipid and apoB-100 molecules, and its periphery is surrounded by hydrophilic apo (a). The two are covalently disulfide bonded Connection; where apo (a) is a characteristic glycoprotein component of lipoprotein (a), mainly composed of a characteristic structure called Kringle, Kringle is composed of 80-114 amino acid residues, relying on three internal disulfides The keys are stable. [0004] Li...
