Journey.Crops are carried out with the key of basic research, first consists in these large biological molecules and to be distributed in plant and the sight of structure
Examine process.
Immunofluorescent Antibody labelling technique is that fluorescein is formed immune mark chemically with specific antibody covalent bond
Remember antibody, and according to the principle of Ag-Ab specific bond, antigen is marked with fluorescein, and utilize fluorescence microscope
Specific fluorescent is observed, so as to intuitively observe distributed process of the antigen in plant.Due to spy of the antigen-antibody effect with identification
The opposite sex, and no particular requirement is formed for antigen, therefore, which has in terms of crop plant structure composition is parsed
Wide applicability.
At present, the application of fluorescence antibody labelling technique is ripe day by day, but traditional detection method determines this
The limitation of detection, i.e., observed by immunofluorescence, can only show the Germ distribution of single structure, obtained relevant information
It measures less than normal and single, the interaction between structure and Relative distribution intuitively can not be observed on the whole, this pole
The earth limits the application of this technology.

Beneficial effects of the present invention
1st, for immunofluorescence technique of the invention compared with original monoclonal antibody immunofluorescence dyeing, the method for the present invention is glimmering using difference
Light marks different polysaccharide molecules respectively, can directly observe the Relative distribution between two kinds of polysaccharide, conducive to find polysaccharide between can
It existing can interact.
Though the 2, the method for the present invention is that two kinds of polysaccharide structures are carried out while dyed based on two kinds of antibody, it is carried out at the same time dye
The sugared structure of color depends on the secondary antibody type that can mutually distinguish, and theoretically, secondary antibody type is more, while the sugared structure dyed is just
It is abundanter.The method of the present invention will lay the first stone to develop while carrying out immune labeled method for a variety of sugared structures later.
