Function and principle of protein analyzer

Protein analyzer laboratory equipment, mainly used for the quantitative analysis of biomolecules such as proteins, can provide more accurate and comparable measurements about samples.
The principle of the protein analyzer is to use radioactive isotope labeling and electrophoresis technology to conduct qualitative and quantitative analysis of various proteins in protein samples. The specific principle is as follows:
1. Radioimmunoprecipitation (radioimmunoassay, RIA): RIA technology is based on antigen-antibody reaction, using radioactive isotopes to label antigens or antibodies, and detecting the presence of various proteins in the specimen through autoradiography technology.
2. Enzyme linked immunosorbent assay (ELISA): Enzyme linked immunosorbent assay (ELISA) is an analysis method that combines the specificity of the antigen-antibody reaction with the catalytic effect of the enzyme. The content of various proteins in the sample can be accurately determined.
3. Two-dimensional gel electrophoresis: A technique for separating and displaying complex protein bands by two-dimensional gel electrophoresis.
