Biotin protein purification
WebThe (strept)avidin-biotin interaction has been widely used for decades in biological research and biotechnology. Therefore labeling of purified proteins by biotin is a powerful way to achieve protein capture, immobilization, and functionalization, as well as multimerizing or bridging molecules. WebBiotin forms a very strong bond with both streptavidin and avidin molecules and this property can be utilized for affinity purification. As biotin is a small molecule, it is unlikely to affect protein functionality 4 . Another valuable tag is the Strep-tag.

WebBiotin was added at 20 nM, and IPTG was added at 0.5 μM for preparation of cells for native form protein purification and at 1 mM otherwise. E. coli strains were grown as described previously ( 16 , 19 ). WebThe Streptavidin-Binding Peptide (SBP)-Tag is a 38- amino acid sequence that may be engineered into recombinant proteins. Recombinant proteins containing the SBP-Tag bind to streptavidin and this property may be utilized in specific purification, detection or immobilization strategies. [citation needed]
