Description
Technical field
The utility model relates to technical field of medical instruments, is specifically related to a kind of reaction cup detected for specific protein.
Background technology
Plasma D-dimer content is one of catabolite of fibrinolysin hydrolytic crosslinking fibrin formation, is metabolin specific to Secondary cases fibrinolytic.The reliability index that the change of Plasma D-dimer Levels can be used as hypercoagulative state in body and differentiates as primary and Secondary cases fibrinolytic, also can be used as the observation index of thromboembolism treatment effect.Detect Plasma D-dimer Levels and have important clinical meaning for aspects such as the diagnosis of disease, efficacy determination and prognosis evaluations.
The detection method of DDi builds on nineteen eighty-three, adopts immunology principle, detectable antigens content.The analytical approach of DDi antigen is a lot, mainly contains Latex Agglutination, enzyme linked immunosorbent assay (ELISA) Micelle growth and immunoturbidimetry.Wherein latex agglutination be with special monoclonal antibody bag by latex particle, after DDi in sample combines with it, there is latex agglutination, DDi content sample can be judged from latex agglutination extension rate.ELISA method is that the first antibody of anti-DDi is coated in solid phase carrier, react with enzyme mark the second anti-D-dimer antibody again after combining with it until DDi in sodium citrate anticoagulate plasma sample, form antibody-antigene-enzyme labelled antibody sandwich complex, quantitative measurement DDi content after last plus enzyme substrate colour developing.Micelle growth is a kind of DDi detection method compared with new development, anti-D-dimer antibody is coated on the test card containing perforated membrane, plasma specimen is by testing after card well adds, DDi in film in antibody capture sample, the monoclonal antibody of anti-another epitope of DDi of colloid gold label is added after washing, be combined and aobvious redness with captured DDi molecule, its colour developing degree is directly proportional to DDi content in sample, through standard card comparison or by special detection measurement amount, can quantitative measurement DDi content.These 3 kinds of methods differ from one another, and latex agglutination test is simple and efficient, are applicable to emergency treatment inspection, but can only sxemiquantitative, and susceptibility is slightly low.ELISA method susceptibility is high, measure accurately, can quantitatively detect, but operation requirements is strict, detecting step is loaded down with trivial details time-consuming, can not meet emergency treatment inspection needs.
The Cleaning Principle of immunoturbidimetry is each emulsion particle diameter (0.1 ± 0.02) μm absorption 2 DDi specific antibodies, the diameter of this particle is less than detection light beam wavelength (540nm), thus when light beam is absorbed through only there being the light wave of trace during latex particle suspension.Determined antigen (DDi) in solution and latex particle adsorb antibodies are combined into condensate, this polymeric diameter is much larger than lambda1-wavelength, thus the absorbed amount of incident light increases greatly, and the absorbance of increase can reflect that determined antigen is at the content by sample product.Therefore, immunoturbidimetry is detected by instrument, has the advantages such as simple to operate, quick, stable, antibiont interference performance is strong, quantitatively can detect the content of DDi, be convenient to clinical observation medication, be applicable to large batch of specimen examination.
