Biotin conjugation site
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 … WebThis procedure is a guideline only.

WebPrepare a biotin standard curve. Add 250 μL of the HABA solution to 10 mL of the avidin or streptavidin solution. Incubate the mixture at room temperature for 10 min and then withdraw two 0.9-mL aliquots. Add 100 μL of the phosphate buffer (pH 6.0) to each aliquot and determine the A 500 of the samples. WebProduct overview. Biotin Gold Conjugate (40nm, 10 OD) (ab186922) is a unique coated nanoparticle that has an avidly bound protective surface coat which can withstand the most extreme conditions (e.g. 2.5M NaOH at 70°C for ~2 hours). By covalently attaching biotin ligand to the surface coat the resulting Gold-Biotin nanoparticles inherit the ...
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 …
