Description
Technical field
The utility model belongs to field of immunodetection, is specifically related to a kind of high sensitivity lipoprotein phospholipase A2 immunochromatographiassay assay quantitative detection test paper.
Background technology
Lipoprotein phospholipase A2 (Lipoprotein-associated phospholipase A2, Lp-PLA2) be phospholipase A 2 (phospholipase A2, PLA2) a member in superfamily, a kind of serine lipase be made up of 441 amino acid residues, relative molecular mass is 45.4kD.Lp-PLA2, as a kind of new inflammatory reaction mark, all plays effect in several Main Stage of atherosclerotic (atherosclerosis, AS).
Lp-PLA2 produces primarily of macrophage and lymphocyte, in early days about in the research of Lp-PLA2 and As because Lp-PLA2 can be hydrolyzed pro-inflammatory cytokine as platelet activating factor (platelet activating factor, and the relevant oxidized phospholipids of structure PAF), therefore be once considered to suppress inflammatory reaction, even can suppress atherosclerotic formation, therefore be also referred to as platelet-activating factor acetylhydrolase (platelet activating factor acetylhydrolase, PAF-AH).But research has in recent years confirmed that effect that Lp-PLA2 is larger is to promote generation and the development of atherosclerotic (atherosclerosis, AS).
At present, show about the experimental study of Lp-PLA2 and epidemiological study, Lp-PLA2 has the effect promoting that coronary atherosclerosis occurs and develops, it is the hazard identification thing of a new AS, the risk of energy independent prediction AS, may become an independently measurement index in the clinical decision in future.
The common method of current detection lipoprotein phospholipase A2 has:
1 enzyme linked immunosorbent assay
Enzyme-linked immunosorbent assay is based on immunological response, antigen and antibody specific is combined the experimental technique that a kind of susceptibility of combining with the efficient catalytic product effect of zymolyte is very high.Utilize Lp-PLA2 antigenicity to prepare specific antibody, directly measured the protein content of enzyme in blood by immunological method.
2 Immunity transmission turbidity
Immunity transmission turbidity is that detection method is commonly used in laboratory.Immunity transmission turbidity is also a kind of immunoprecipitation assay of trace.Itself and rate nephelometry are unlike the content reflecting determined antigen with the light quantity measured through solution.When light therethrough reaction system, the antigenantibody complex in solution can be absorbed light and be reflected, and transmitted light is reduced.Immune complex is more, and the light of absorption is more, and transmitted light is fewer, and the available absorbance of this change represents.If antibody amount is fixed, survey absorbance and be directly proportional to the amount of immune complex, be also directly proportional to the amount of determined antigen.Compare with the antigen standard of a series of concentration known, namely can measure examined object content.
Biotin-avidin system (biotinavidin system, BAS) is a kind of new bio reaction amplification system.Along with the appearance of various biotin derivative, BAS is widely used in each field of medical science very soon.This system is applied to SABC, enzyme linked immunological, fluorescence immunoassay, in the detection techniques such as radio-immunity, the susceptibility of above technical method, specificity and stability can be improved significantly, make method easier, contribute to clinical quick diagnosis, and be beneficial to and carry out extensive epidemiology survey, become the immunoreactive powerful of research.Because BAS detection system economy is quick, pollute without radiating matter again, do not need complex instrument, fully show the great potential of this system and the possibility of application.
Biotin-avidin system Cleaning Principle: BAS is on the basis of conventional ELISA principle, in conjunction with the height amplification between biotin and Avidin, and a kind of detection system set up.Avidin is a kind of alkaline glycoprotein extracted in ovalbumin, and molecular weight is 68kDa, is made up of 4 subunits, have very high affinity (binding constant is up to 1015M-1) to biology.Biotin is very easily combined with covalent bond with protein (as antibody etc.).Like this, the Avidin molecule combining enzyme and the biotin molecule being combined with specific antibody produce and react, both served multistage amplification, the colour generation due to the catalytic action of enzyme when running into corresponding substrate, reaches the object detecting unknown antigen (or antibody) molecule again.Streptavidin is and the affine a kind of protein have similar biological properties, in Streptavidin molecule the same as Avidin, every bar peptide chain can in conjunction with a biotin, because nearly all material for marking all can combine with Avidin or streptavidin.Utilize biotin-avidin system to develop lipoprotein phospholipase A2 detection examination fast diagnosis reagent and there is no report.
