Purification or Removal of Biotin and Biotinylated Substances

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 attache… WebBiotin is a vitamin (Vitamin H, Vitamin B7, Coenzyme R) that is present in small amounts in all living cells and is critical for a number of biological processes including cell growth and the citric acid cycle.
