Description

"In contrast to Fmoc-Lys(biotin)-OH, this novel biotin-labeled amino acid has excellent solubility in DMF and other solvents used in SPPS [1]. The PEG-spacer restricts hindrance between the peptide and avidin, leading to better biotin binding. Furthermore, the hydrophilic nature of the PEG minimizes non-specific interactions that can arise from the spacer group becoming buried in the hydrophobic pocket of proteins.For recent applications, please see [2 - 4].The product number for this product was previously 04-12-1250.To obtain a certificate of analysis (CoA) of a lot that begins with the letter ""A"", please select the option in the right hand menu ""Request a COA for Lot#s starting with A""."
