Biotin and streptavidin interaction
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… WebDec 15, 2016 · The simulated extinction cross section presented in Fig. 2 C shows LSPR shifts of 3 nm and 12 nm after interaction with biotin (spectrum b) and streptavidin (spectrum c), respectively, in good agreement with experimental results. 3.3.
