Biotin conjugation site
WebJul 20, 2008 · unmodified trastuzumab. The purified proteins were conjugated to biotin-maleimide, and the extent of conjugation was quantified by LC/MS analysis. As 9 of the 13 THIOMABs showed 490% conjuga-tion efficiency, they should be as suitable for site-specific conjugation of thiol reactive probes as the HC-A114C variant described below 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 …

WebThe researchers produced a trastuzumab–biotin conjugate by incorporating the peptide tag onto the C terminus of the heavy chains of trastuzumab and reacting it with DBCO-(PEG) 4-biotin. The reaction only generated 90% heavy-chain mono-adduct and no reaction between liberated thiols and cyclooctyne was observed. The resulting conjugate exists ...
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. in my father\\u0027s kitchenWebThis product is manufactured by Expedeon, an Abcam company, and was previously called Lightning-Link ® Rapid Biotin Type A Labeling Kit. 370-0005 is the same as the 100 µg size. 370-0010 is the same as the 3 x 100 ug size. 370-0030 is the same as the 3 x 10 ug size. 370-0015 is the same as the 1 mg size..
