The invention discloses a kit for detecting homocysteine. The kit comprises a reagent R1 and a reagent R2, wherein the reagent R1 contains the following components and concentrations: 10-200mmol/L of buffer solution, 1-10mmol/L of homocysteine reducing agent, 0.1-15mmol/L of serine, 0.2-5.8mg/L of coenzyme, 5-100KU/L of lactic dehydrogenase, 0.01-0.8g/L of reducing coenzyme I, 5-150g/L of enzyme stabilizer, 1-100g/L of surface active agent and 0.1-5g/L of preservative; the reagent R2 contains the following components and concentrations: 10-200mmol/l of buffer solution, 0.2-5.8mg/L of coenzyme, 1-100KU/L of cystathionine beta-synthetase, 1-100KU/L of cystathionine beta-lyase, 5-150g/L of enzyme stabilizer, 1-100g/L of surface active agent and 0.1-5g/L of preservative. The kit disclosed by the invention has the advantages that the use amount of enzyme can be reduced, the stability of detection can be improved, the sensitivity of cyclic detection can be improved, the accuracy is high and the application range is wide. The method is good in correlation with an HPLC (High Performance Liquid Chromatography) method, pretreatment for a sample is not needed, the detection on a full-automatic biochemical analyzer is automatic and the speed is high.
Description
technical field [0001] The invention relates to a kit for detecting homocysteine. Background technique [0002] Homocysteine (HCY) is a sulfur-containing amino acid and a metabolite of methionine. Recent studies have found that HCY can cause birth defects such as neural tube defects (NTDs) and congenital heart defects (CHD), and HCY is also closely related to the pathogenesis of atherosclerosis. [0003] As early as 40 years ago, Dr. McCully first discovered and discussed the relationship between homocysteine and the occurrence and development of cardiovascular diseases. Patients with homocystinuria are often in their teens to twenties. Severe cardiovascular disease occurs in adolescence. Recent studies have found that 10-20% of patients with cardiovascular disease are not related to risk factors such as cholesterol levels, smoking and high blood pressure, but are caused by elevated homocysteine. Genetics and eating habits are the main reasons for the increase of homo...
