Biotinylation Guidelines—Creating Biotinylated DNA

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 biotin-binding by AVIDIN is not only strong, specific, and rapid, but resilient too, withstanding proteolytic enzymes and extremes of temperature and pH.
