(3) There is some controversy in evaluating the infarct size of AMI by the serum CK-MB level. It is generally believed that the smaller the infarct size, the earlier the CK-MB peak time and the shorter the recovery time
3. CK-MB is not completely specific to myocardium, but also exists in a small amount in skeletal muscle

Abstract

The invention discloses a quantitative creatine kinase-myoglobin (CK-MB) determination kit. The kit is characterized in that the kit contains CK-MB magnetic separation reagent, enzymatic reactant, reaction enhancer, diluent, CK-MB calibrator, CK-MB quality control material, cleaner concentrate and substrate solution. The invention also discloses a preparation method for the kit. The kit integrates the chemiluminescence technology with immunomagnetic beads to provide a homogeneous phase-approximating reaction system. Compared with the prior art, the kit has higher assay sensitivity and specificity, and achieves better performance parameters, and mover, the product cost is greatly reduced.

Description

technical field [0001] The invention relates to a kit for measuring serum and a testing method thereof, in particular to a kit for measuring the content of creatine kinase isoenzyme (CK-MB) in human serum and a testing method thereof. Background technique [0002] The molecular weight of human creatine kinase isoenzyme is 85745. CK-MB is mainly distributed in the myocardium. When the myocardium is injured, CK-MB is released into the blood, and starts to increase after 3-8 hours, and can last for 3-5 days. The combined detection of troponin, myoglobin, and creatine kinase isoenzyme can detect myocardial damage this morning. CK is a dimer composed of M and B subunits, and two different subunits make up three isozymes. CK-BB (CK1) mainly exists in brain tissue CK-MB (CK2) mainly exists in cardiac muscle CK-MM (CK3) mainly exists in skeletal muscle tissue In addition, there is an isoenzyme (CK-MiMi) in mitochondria. The content of CK-MB in different parts of the myocardium i...
