Abstract
The invention discloses application of a microdialysis sampling-flow injection chemiluminescence combined method in determination of the affinity between a small-molecule hapten and a monoclonal antibody and a specific determination method. A combined analysis method is used for researching affinity between the small-molecule hapten and the monoclonal antibody in a homogeneous phase system under a label-free condition and is simple, convenient, stable and sensitive. Compared with existing methods for determining the affinity of antibodies, the method has the advantages that the antibodies do not need to be labeled by virtue of signal molecules such as enzyme, and the small-molecule hapten and a carrier protein do not need to be coupled for coating, so that the tedious works of labeling, coupling and the like can be omitted; and more importantly, the real combination condition between the hapten and the antibody can be objectively reflected, expensive instruments are not required, and the cost is relatively low. According to the application and the method, a simple, rapid and objective analytical technical measure is provided for the performance evaluation of the antibodies, and meanwhile, the application field of the microdialysis sampling technique is newly extended.

Application in the affinity of the monoclonal antibody for small haptens measures.
Background technology
Monoclonal antibody technique is a kind of immunological technique, and it will produce the same tumor cell of single bone-marrow-derived lymphocyte of antibody
Hybridization, it is thus achieved that can produce antibody, again can the hybridoma of infinite multiplication, and produce antibody with this.This technology is antibody
Molecules research provides brand-new means, is greatly promoted immunologic development.In recent years, monoclonal antibody technique
Application widely has been obtained in immune detection, immunization therapy, the field such as isolated and purified.Preparation and sieve in monoclonal antibody
During choosing, one of most important work is the binding affinity to specific antigen of the monoclonal antibody to different cell strain secretions
This key index is evaluated, and it has highly important directive significance for the exploitation application of monoclonal antibody.
It is presently used for measuring the method for binding constant between Ag-Ab and mainly includes competition binding method, rhodanate eluting
The different Phase Analysis Method based on antibody labeling such as method, non-competing enzyme immunoassay (EIA).In recent years, also there are some cold methods
For measuring affinity of antibody, its principle is similar with foregoing tags method, difference be antibody without with signal probe labelling,
But after antigen and antibodies, measure sensing with the non-marked method such as surface plasma body resonant vibration, QCM
Bioconjugation reaction on device interface, research antigen and the cohesive process of antibody according to this.The drawback of labelling method is, all antibody
Being required to be marked with signaling molecules such as enzymes, one to carry out labeling process loaded down with trivial details, and two carry out labelling may affect the biological activity of antibody,
The measurement result obtained is difficult to objectively respond between Ag-Ab real affinity.Regardless of whether be labelling method or non-marked
Method, is required for being fixed on antigen ELISA Plate or sensor surface.If antigen is small haptens, owing to they are difficult to
ELISA Plate or sensor surface are the most fixing, it usually needs form artificial complete antigen rear with carrier protein couplet and can be used for wrapping
Quilt, and coupling may bring problems with: first, coupling process more bothers；Secondly, coupling may destroy antigen molecule structure
In antigenic determinant, or, antigenic determinant and coupling protein hypotelorism, the association reaction between Ag-Ab is produced
Sterically hindered, all can not truly reflect the affinity of antibody.Therefore, it is necessary to development is a kind of without to small haptens and anti-
