WebApr 15, 2012 · Streptavidin–biotin conjugation is an alternative for a site-specific reaction which can be conducted by employing derivatized PEGs with biotin and biotinylated antibodies (i.e. CD133-Biotin). In this way, streptavidin (with four binding sites for biotin) can bridge two biotinylated reagents and form a site-specific PEGylated antibody. WebBiotin (blue) is conjugated to a reactive group (red) either directly or with additional chemical structures (black) to increase the spacer arm length. The reagent shown is …

Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates (e.g., NHS-coupling gives biotinylation of any primary amines in the protein). Enzymatic biotinylation results in biotinylation of a specific lysine within a certain sequence by a bacterial biotin ligase. Most chemical biotinylation reagents consist of a reactive group attached …
WebSep 24, 2024 · Although these labelling techniques are very simple and efficient for adjoining biotin to avidin conjugates, identical biotin binding-site of avidin may raise some issues of undesirable conjugation of biotinylated complexes due to its random cross-linking [26].
