Background information

Biotin NovaTag™ resin is an ideal tool for the synthesis of peptides labeled iwth biotin. As the biotin moiety is incorporated into the linker, its use eliminates the problems associated with biotin-labeling of peptides, namely poor solubility and sluggish coupling kinetics of biotin and its derivatives.

Attachment of the first amino acid should be effected using HATU/DIPEA. Following peptide assembly under standard Fmoc SPPS conditions, cleavage with TFA affords the peptide labeled with biotin.

Biotin-PEG NovaTag™ resin incorporates a PEG spacer into the peptide, which leads to products having better solubilities compared to those prepared using standard biotin derivatives [1]. Furthermore, the PEG spacer reduces steric hindrance between the peptide and avidin, leading to better binding of biotin. For recent applications, see [2, 3].

The product number for this product was previously 04-12-3908.
