Abstract

The invention discloses a detection kit for a plasminogen activator inhibitor. The detection kit is characterized by comprising a reagent R1 and a reagent R2, wherein the reagent R1 comprises a firstbuffer solution A, a first buffer solution B, sodium chloride, a stabilizer, a surfactant, an accelerator and a preservative; and the reagent R2 comprises a latex microsphere antibody conjugate, a coupling buffer solution, a blocking solution and a stock solution. The detection kit has the advantages that a plasminogen activator inhibitor antibody is connected with biotin, streptavidin is connected with latex microspheres, and mixed reaction is performed, so that the sensitivity of the detection reagents can be effectively improved, the repeatability can be improved and the linear range can reach 1.30-130.00 ng / mL.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a detection kit for plasminogen activator and a preparation method. Background technique [0002] Plasma plasminogen activation inhibitor (PAI) is divided into PAI-1 and PAl-2, among which PAI-1 plays a major role in regulating plasma fibrinolytic activity. PAI-1 is a single-chain globular glycoprotein, and tissue-type plasminogen activator and PAI-1 are a pair of key substances that regulate fibrinolytic activity, both of which are synthesized by vascular endothelial cells and released into the blood. [0003] The existing reagents for detecting plasminogen activator inhibitors use latex microspheres to directly couple plasminogen activator inhibitor antibodies, which have the defects of poor sensitivity and linear range, which limits its application. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0004] The purpos...
