Allergen IGE antibody detector classification

Allergen IgE antibody detectors can be mainly divided into the following categories:

1. Immunofluorescence detector: The fluorescent dye-labeled IgE antibody is used to emit a fluorescent signal after binding to the allergen, and the concentration of the IgE antibody is quantitatively determined by detecting the fluorescence intensity.

2. Enzyme-linked immunosorbent assay (ELISA): After the enzyme-labeled IgE antibody is combined with the allergen, a visible color reaction is produced by adding a substrate, and then the intensity of the color is observed with a photometer or microscope to quantitatively measure the IgE antibody. concentration.

3. Radioimmunoassay (RIA): After the radioactive isotope-labeled IgE antibody is combined with the allergen, the concentration of the IgE antibody is quantitatively measured by measuring the radioactivity of the radioactive isotope.

4. Immunoelectrophoresis detector: Use the principle of electrophoresis to separate various IgE antibodies and allergens, and judge the reaction between allergens and IgE by observing the electrophoresis pattern.

The above is the classification of common allergen IgE antibody detectors. Different types of detectors have their own characteristics and applicable occasions. You can choose a suitable detector according to actual needs to detect allergen IgE antibodies.
