Biotin uv absorption
WebBiotinylation. In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule due to the small size of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an extremely ... WebBiotin –streptavidin system (BAS) has been introduced and developed for application purposes and to try to understand the special nature of this ultrahigh-affinity interaction …
