Features of EZ-Link Sulfo-NHS-Biotin: • Protein labeling —biotinylate antibodies to facilitate immobilization, purification or detection using streptavidin resins or probes WebBiotinylation is the labeling of biotin to a molecule of interest such as a protein, antibody, peptide, or other biomolecule (Figure 1). Biotinylated proteins typically retain biological …
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 … See more Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates … See more Reaction conditions for biotinylation are chosen so that the target molecule (e.g., an antibody) is labeled with sufficient biotin molecules to purify or detect the molecule, but not so much that the biotin interferes with the function of the molecule. HABA assay See more Purification The biotin tag can be used in affinity chromatography together with a column that has avidin (or streptavidin or neutravidin) bound to it, which is … See more The non-covalent bond formed between biotin and avidin or streptavidin has a binding affinity that is higher than most antigen and antibody bonds and approaches the strength of a covalent bond.
