Kit for testing acute coronary artery complex by insulin growth factor combing protein-4 hydrolase

Abstract

A reagent kit is composed of standard products, multiple clone antibody encapsulated plate, enzyme single clone antibody, quality control productand auxiliary reagent. The present invention also provides preparation method of kit and inspection method. The reaction method of quantitative biantibody sandwich enzyme linked immunosorbent is applied by the kit.

Description

technical field

[0001] The invention belongs to the field of medical and biological detection, in particular, the invention relates to a detection of acute coronary syndrome by using insulin growth factor binding protein-4 (i.e. Insuline Growth Factor Binding Protein-4, referred to as IGFBP-4) hydrolase The kit can be used for the diagnosis of acute coronary syndrome, especially for the assessment of the risk of acute myocardial infarction, and the invention also relates to a preparation method and a measurement method of the kit. Background technique

[0002] Acute Coronary Syndrome (ACS) has a high mortality rate in European and American countries, and it has a tendency to increase significantly in my country in recent years. ACS refers to the pathological phenomenon of atherosclerotic plaque shedding, platelet aggregation, and thrombus formation, resulting in coronary artery stenosis and blockage, myocardial ischemia and myocardial infarction. Clinical manifestations can...

Embodiment 2

[0079] Example 2: Example of use of IGFBP-4 proteolytic enzyme quantitative ELISA kit

[0080] 1. Washing buffer preparation: dilute the concentrated washing buffer provided in the kit with distilled water 20 times.

[0081] 2. Dissolve the first-point lyophilized powder (concentration: 64mIU / L) of the standard provided in the kit with 500 μl of washing buffer, and then perform doubling dilutions 4 times. The standard curve in the kit is composed of 5 different concentrations of IGFBP-4 proteolytic enzyme standards, the concentrations of each point of the standard curve are 64mIU / L, 32mIU / L, 16mIU / L, 8mIU / L, 4mIU / L.

[0082] 3. Dilution of quality control products: Dissolve the lyophilized powders of low and high quality control products provided in the kit with 110 μl of washing buffer respectively.

[0083] 4. Antigen-antibody reaction: Add 100 μl of diluted standard substance, quality control substance, or serum sample to be tested into the microwells of the antibody-coate...
