Description
Technical field
The present invention relates to vitro detection field, particularly relate to a kind of anti-endometrial antibodies chemiluminescence immunoassay detectable
Box and preparation method thereof.
Background technology
Anti-endometrial antibodies (AEAb) is a kind of autoantibody, and targeted antigen is in endometrial glandular epithelial cells
A kind of progestogen dependent protein, entopic endometrium is to body no antigen, but the endometrium of dystopy can conduct
Antigenic stimulus body immune system, produces special anti-endometrial antibodies not only anti-with ectopic endometrium generation antigen-antibody
Should, also can combining with the antigen site in entopic uterine veil cell simultaneously, activating complement system, local produces immunity
Pathological change, directly affects the function of endometrial gland, thus causes implantation of ovum failed or sterile, finally with inapparent
Early abortion and come to an end.Therefore anti-endometrial antibodies detection also has important meaning to clinical diagnosis with treatment sterility and infertility patient
Justice.
The common methods of Clinical detection anti-endometrial antibodies has enzyme linked immunosorbent assay, enzyme-catalyzed chemical luminescence method at present,
But in place of these methods all also exist some shortcomings.
One, enzyme linked immunosorbent assay
Enzyme linked immunosorbent assay (ELISA) is widely used, but the method there is also following weak point:
(1) use 12 × 8 types, 6 × 8 types, 8 × 12 types or complete plate 96 hole Special micro porous plate as antigen coated apparatus with anti-
Answer container, 12 batches, 6 batches, 8 batches or imposite first use can only be divided in use, it is impossible to carry out independent, single
The detection of person-portion;
(2) reagent type used by quantitative determination is more, and each detectable will contain with reagent bottle, and often makes
Being required for changing imbibition nozzle during with a kind of reagent to be filled into respectively in the micropore of microwell plate, not only reagent bottle kind is many, filling
The operation of reagent is the most loaded down with trivial details;
(3) lack the corresponding mark to detection information, can only just will appreciate that by the mark checking test kit external packing box or know
Know product batch number and the effect duration information of detectable, and the information known is uncontrolled during detection, has the biggest
Randomness;
(4) detectable is in open space during detection, easily causes the cross-contamination between various reagent and shadow
Ring the accuracy of testing result;
(5) detection process uses manual operations, and the dosage of reagent or sample is not bery accurate, and operating process is the most loaded down with trivial details and multiple
Miscellaneous, it is susceptible to bust, accuracy and the precision of testing result are poor;
(6) in the quantity configuration and use of detection project reagent set, it is item number × 48/96 person-portion, if needing inspection
Survey 10 projects, then configuration and the use number of reagent must be 10 × 48/96 person-portions, if the most a sample needs to detect 10
Individual different project, it is also desirable to the reagent of configuration 10 × 48/96 person-portions, the shortcoming that there is inadequate economical rationality.
Two, chemoluminescence method
Chemoluminescence method can be divided into direct chemiluminescence and enzyme-catalyzed chemical luminescence by principle of luminosity.
Enzyme-catalyzed chemical luminescence mainly has horseradish peroxidase (HRP) and alkali phosphatase two kinds, but has certain office
Sex-limited, horseradish peroxidase major defect is: luminol, also can be by H2O2 in the case of not having horseradish peroxidase
Aoxidizing self luminous, background is of a relatively high, affects signal to noise ratio, and kinetics is complicated, and influence factor is many, and result is not sufficiently stable,
Obtain highly sensitive and plateau length substrate to be not easy.Alkali phosphatase major defect is: substrate reach plateau time
Between long, substrate cost is high, causes testing cost high, patient burden's weight.
Acridinium ester is compared enzyme-catalyzed chemical luminescence as the direct chemiluminescence of label and is had detailed advantage, mainly shows
: reaction need not catalyst, as long as alkaline environment can be carried out, is swift in response, and background luminescence is low, and signal to noise ratio is high, disturb because of
Element is few, and reagent stability is good, can be with two-point calibration, and system is simple, exciting liquid low cost, acridinium ester easily and protein bind, and
After connection, photon productivity does not reduces.
