Biotin-avidin

Avidin is used in various laboratory techniques, such as:Biotinylation,ELISA,Western Blotting,Purification.
Biotinylation: Labeling proteins or nucleic acids with biotin for detection or isolation.
ELISA: Enzyme-linked immunoassays often use the avidin-biotin system in detection schemes.
Western Blotting: Biotinylated antibodies can be detected using avidin conjugated to an enzyme or a fluorescent tag.
Purification: Biotinylated molecules can be easily purified via avidin-coated surfaces.
