Problems solved by technology

The most common method is the sequencing method, which is low in cost, but takes a long time and is not sensitive; the high-resolution melting curve method requires relatively high equipment requirements, which is not conducive to clinical promotion; the traditional fluorescent PCR method is widely used in clinical practice. However, the detection sensitivity is not high

Abstract

The invention eblogns to the technical field of biology and specifically relates to a human phlebothrombosis risk gene F5 and PAI-1 polymorphism detection kit as well as a preparation method and application thereof. The kit is prepared from a detection reagent, a positive control product and a negative control product, wherein the detection reagent is used for amplifying gene F5 and PAI-1 polymorphism related to the human phlebothrombosis risk, wherein the detection reagent applied to the F5 gene polymorphism is prepared from a primer sequence, a PNA sequence and PCR reaction liquid; the primer sequence is used for amplifying an rs6025 site of F5 gene; the detection reagent applied to the PAI-1 gene polymorphism is prepared from a primer sequence, a PNA sequence and PCR reaction liquid; the primer sequence is used for amplifying an rs17999762 site of the PAI-1 gene. The kit disclosed by the invention is used for detecting the human aspirin resistance gene polymorphism and has the advantages of high flexibility, high specificity, convenience in operation, reliable results and the like; furthermore, detection can be finished within 1 hour, and result reading is simple and objective.

Description

technical field [0001] The invention belongs to the technical field of biomedical clinical detection, and in particular relates to a human venous thrombosis risk gene F5 and PAI-1 polymorphism detection kit and its preparation method and application. Background technique [0002] The formation of thrombus is the body's normal protective response to vessel wall damage. When the procoagulant stimulus exceeds the body's natural protection ability to inhibit thrombus formation, the thrombus grows excessively beyond the physiological range and causes damage to the body. The formation of blood clots (thrombosis) in veins is venous thrombosis, and the risk factors for venous thrombosis are mainly divided into two categories: one is acquired risk factors; the other is genetic risk factors, such as anti-protein S deficiency (type I) , coagulation factor ⅤLeiden (FVL), dysfibrinogenemia and other coagulation-related diseases. Among them, FVL is the most common genetic risk factor for...
