Biotin and streptavidin interaction
WebNational Center for Biotechnology Information Among the most common uses of streptavidin are the purification or detection of various biomolecules. The strong streptavidin-biotin interaction can be used to attach various biomolecules to one another or onto a solid support. Harsh conditions are needed to break the streptavidin-biotin interaction, which often denatures the protein of interest being purified. However, it has been shown that a short incubation in water above 70 °C will reversibly break th…
