As a solid-phase support, it is widely used in experiments such as Western blot, Southern blot, Northern blot, dot blot hybridization, and colony transfer to detect and analyze proteins and nucleic acids.
In the field of disease diagnosis, it can be used to prepare diagnostic membrane strips to detect pathogen antibodies or tumor markers, enabling rapid immunodiagnosis. In the quality control of biopharmaceuticals, it is used to detect the purity, integrity, and impurities of recombinant protein drugs, antibody drugs, and other products, ensuring drug safety and efficacy.
In proteomics research, it is used to analyze differences in protein expression profiles among different samples and can be used to detect post-translational modifications of proteins and to study protein-protein interactions.
