A kind of full-automatic immunoblotting assay instrument and using method and application
Technical field
The present patent application relates to a kind of full-automatic immunoblotting assay instrument and using method and application, belongs to medical treatment detection device technical field.
Background technology
Western blotting (immunoblotting) claims again Western blotting (Western blotting), is according to the method for certain albumen in the specific binding detection of complex sample of antigen-antibody.This method is a kind of new immune biochemical technology growing up in gel electrophoresis and solid-phase immunoassay technical foundation.Because Western blotting has the high resolution of SDS-PAGE and the high specific of solid-phase immunoassay and susceptibility, now become a kind of routine techniques of analysis of protein.Western blotting is usually used in identifying certain albumen, and can carry out quantitative and semi-quantitative analysis to albumen, in conjunction with chemiluminescence detection, and the expression difference of more a plurality of samples albumen of the same race simultaneously.
Western blot detects by antibody and the epitope generation specific immune response that the target protein that is attached to solid support presents, and whole process comprises: the several parts of the separation of protein, electrotransfer, immunology detection and input.At present, detection for Western blot has manual detection and instrument to detect two large classes, the method manually detecting need to be changed different reagent, operation has increased experimenter's working strength and has lost time frequently, and manual operations is loaded down with trivial details and complicated, people contacts many with tool latent infection article, detect poor stability; Current Western blotting detecting instrument used clinically, although be called " automatically ", in fact can not complete detecting the drying function of sample, and after reaction finishes, detection sample need to be shifted out to instrument and carry out other determination and analysis, waste time and energy and operate inconvenience.
