Description
Technical field
The present invention relates to the biochemical indicator that ApoA5 (ApoA5) is diagnosed as hypertriglyceridemia (HTG), the technology of preparing that ApoA5 monoclonal antibody is right, the immunochromatography reaction technology of colloid gold label colour developing and utilize the antibody of ApoA5 to carry out the technical field of diagnosing high triglyceride (HTG), particularly one is used for the detection agent plate of diagnosing high triglyceride (HTG).
Technical background
The project detecting blood fat clinically has a lot, and the elementary item of each hospital general inspection has T-CHOL (TC), triglyceride (TG), apolipoprotein (Apo) B, Apo AI, lipoprotein (a) [Lp (a)] etc.Survey data research shows, high triglyceride, high cholesterol, low high-density lipoprotein (HDL)-C (HDL-C) and high low-density lipoprotein-C (LDL-C) together constitute the hazards of coronary heart disease.Apolipoprotein (Apo) abnormal with coronary heart disease and apoplexy closely related.Correctly diagnose as early as possible, be conducive to these serious diseases of early prevention and treatment.Apolipoprotein detects the exploitation of reagent, contributes to effective control of coronary heart disease and apoplexy.
Serum ApoAI can represent HDL level, is proportionate with HDL-C, its clinical meaning also broadly similar.But HDL is a series of grain size and the inhomogenous lipoprotein of composition, and under pathological state, HDL subclass often changes with composition, therefore the fixed and HDL-C of going up and down with different paces of ApoAI changes completely proportional.The ratio of ApoB100 nearly 90% is distributed in LDL, so serum ApoB main representative LDL level, it and serum LDL-C level are obvious positive correlation, and the clinical meaning of ApoB level height is also similar to LDL-C.But, in limited instances, high ApoB100 mass formed by blood stasis can be there is and the normal situation of LDL-C concentration, so these two kinds of apolipoprotein reliabilities and accuracy are very not satisfactory.
ApoA5 belongs to ApoAI/CIII/AIV gene group, at liver expression, relevant with HDL/VLDL.The single nucleotide variations (SNP) of ApoA5 gene promoter directly affects triglyceride levels.Experimental study shows, in the blood plasma of expressing the genetically modified mouse of mankind ApoA5, the concentration of triglyceride drops to 1/3rd of contrast mouse, and adds 4 times in the mouse lacking this gene.ApoA5 has very high Sensitivity and Specificity as the etiological diagnosis index of hypertriglyceridemia.
High levels of triglycerides can make little dense low-density lipoprotein (sLDL) concentration raise, and has stronger atherogenicity effect.Triglyceride levels is higher, and the cholesteryl ester in low-density lipoprotein is more.People are verified, and the cholesterol in atherosclerotic plaque mainly comes from low-density lipoprotein, and low-density lipoprotein is maximum containing cholesterol in blood plasma, is also the lipoprotein that atherogenic is the strongest.In addition, epidemiological study shows, high levels of triglycerides makes high-density lipoprotein concentration decline, and high-density lipoprotein concentration is by the impact of triglyceride levels, and both are negative correlation.Recent research shows, blood triglyceride levels is abnormal abnormal closely related with the body intravascular coagulation factor, plasma triglyceride level raises and body intravascular coagulation factor level can be caused to raise, thus promotion blood clotting, and tissue plasminogen activator's inhibitor (PAI) can be made to synthesize increase, suppress fibrinolysis, form hypercoagulative state, promote the generation of coronary heart disease.Have experimental result to show, triglyceride concentration rising 1mmol/L, the cardiovascular unexpected incidence male sex rises 32%, and women is 76%.After the impact correcting high-density lipoprotein (HDL), the level of significance male sex rises 14%, and women is 37%.These results show that the rising of serum triglyceride concentration is the important risk factor of angiocardiopathy.
Primary hypertriglyceridemiapatients patients often has hypertension and insulin resistance simultaneously.Insulin resistance is often referred to patient and tends to non-insulin dependence abnormal carbohydrate metabolism, and such patient often forms coronary artery disease earlier.Usually lipid triad, hypercoagulative state, hypertension, insulin resistance are called metabolic syndrome.Confirm that primary hypertriglyceridemiapatients patients is often associated with other exception in metabolic syndrome.The clinical meaning of hypertriglyceridemia is this.And seeming particularly important as the index ApoA5 directly affecting triglyceride levels, the single nucleotide polymorphism of ApoA5 is expected to as risk indicateing arm and the therapy target reducing serum lipid concentrations.
ApoA5 is applied to clinical practice to reach the quick diagnosis of the cause of disease of hypertriglyceridemia by the right technology of preparing of monoclonal antibody and colloidal gold immunochromatographimethod technology by the present invention, and the object that the angiocardiopathy such as coronary heart disease and apoplexy is is effectively prevented and treated.
Sandwich double-antibody technique is based upon the newer rear antibody technique of biological technical field on monoclonal antibody technique.Double antibody sandwich method application antibody is to identifying that capture antigen is carried out in two sites of antigen, avoid the competition binding in the same site of antibody and antigen, decrease the steric hindrance of antigenic determinant, so more general antigen capture method is more responsive, specificity is stronger, repeatability is better, is particularly useful for the detection of the little sample of antigenic content.The present invention, in conjunction with the antibody pair for ApoA5 of this technological development, more highlights its significance to micro biochemical index (antigen) in detection HTG patient blood.
