Description: The membership of the Association of Biomolecular Resource Facilities was asked to participate in a study focusing on synthesis of a biotin-labeled peptide, and it was suggested that a new strategy, using Rink amide 4-methylbenzhydrylamine resin coupled with Fmoc-Lys(Dde)-OH, be used. This strategy can be used for addition of a variety of labels other than biotin and should prove useful to core facilities. Comparison of the new strategy to other strategies was performed. Biotin labeling has long been assumed to be routine and specific. Despite the assumed routine nature of synthesizing biotinylated peptides, 9 of the 34 samples submitted did not contain any of the correct product. Although synthesis using Fmoc-Lys(Dde)-OH plus biotin generally gave the highest yields, other approaches also yielded a high percentage of the correct product.Therefore, the various strategies are generally comparable. The major advantage of this new approach is that other labels such as fluorescein, dansyl groups, methyl coumarin, and potentially fluorophores and quenchers used for fluorescence resonance energy transfer (FRET) can be directly incorporated into peptides.
