Biotin streptavidin interaction ph
WebApr 7, 2024 · For this purpose, biotin–streptavidin interaction, protein A/G–antibody interaction, His 6-tag protein/NTA/Ni 2+ (Cu 2+) reaction and click reaction are extensively used. Current strategies combine these types of immobilizations in various formats to increase the surface coverage of the anchored biomolecules. WebThe streptavidin-biotin interaction is the strongest known non-covalent, biological interaction between a protein and molecule. The bond formation between biotin and avidin is very rapid and, once formed, is unaffected by wide extremes of pH, temperature, organic solvents and other denaturing agents. Unless derivative forms of biotin or ...
