Description
Technical field
The present invention relates to medical immunology in-vitro diagnosis field, and in particular to a kind of apolipoprotein B detection kit and detection
Method.
Background technology
Turbidimetry is widely used in clinical examination work.It is immunoturbidimetry that application is most common now.
It is all by observing the formation of sediment, aggegation and the generation of haemolysis that the immuno analytical method of early stage is most of
The presence or absence of specific protein and content in testing sample are analyzed in the light scattering caused by aggregate with measure, such as immune to expand
Scattered, immunoelectrophoresis, direct and brief introduction blood clotting, passive hemagglutination, complement fixation test etc., these detection method costs are low, result is easy
In judgement, technically it is easy to grasp, can be widely used for detecting polytype clinical sample.But because above method operation is numerous
It is trivial, time-consuming and sensitivity and poor accuracy and tend to be eliminated.
Immunoturbidimetry overcomes disadvantages mentioned above, and quantitatively accurate automation can be developed with reference to the demand of clinic
Instrument.Therefore, for immunology detection, immunoturbidimetry has immunology antigen, the specificity of antibody binding, has again
Biotrepy feature, during body fluid can be detected in automation biochemical instruments, the micro test substance particularly in blood,
It is a kind of clinical examination practical technique having very much using future.
Immunoturbidimetry (Turbidimetric inhibition immuno assay) is that antigen-antibody combines dynamic survey
Determine method.Its general principle is：When antigen and antibody react and suitable (the general provision antibody of ratio in special dilution system
It is excessive) when, in the presence of the poly- agent of rush of the soluble immune complex of formation in dilution system, separate out, formed micro- from liquid phase
Grain, makes reaction solution turbidity occur.When antibody concentration is fixed, the amount of the immune complex of formation is with the increasing of amount of antigen in sample
Add and increase, the turbidity of reaction solution is consequently increased.Compareed by the turbidity for determining reaction solution with series of standards product, you can meter
Calculate the content of antigen in sample.
The various detecting instruments developed according to the general principle of immunoturbidimetry, developed have been widely used in clinical inspection
The many aspects tested, it is the basic functional principle of Blood coagulation instrument optical method and immunization；It is the load fat in full-automatic biochemical measure
Albumen, haptens and other protein measuring principles；It can also be applied to microorganism detection simultaneously.By accurately to more
Kind material is quantified, and the diagnosis, treatment and prognosis evaluation to many diseases have larger clinical meaning.
The conventional immunoturbidimetry of clinic because its sample dosage is few, can directly on automatic clinical chemistry analyzer batch sample
Analyze, be simple to operate, but the reagent and method established at present all have some shortcoming and defect, are mainly manifested in：
Antibody is easy to cotton-shaped or flaky precipitate occur during preservation, cause antibody performance be deteriorated, repeatability it is bad,
The coefficient of variation (CV) becomes big, directly contributes reagent testing result inaccuracy, and increases filtration step, complex operation, and filters
Antibody may be removed, influences Detection results, patient is affected, it is impossible to meets requirement.
