Fmoc-Cys (StBu) Wang Resin

Wang resins are the standard supports for the synthesis of peptide acids by solid phase synthesis using the Fmoc strategy. Fmoc protected amino acids are linked to Polystyrene-PHB (Wang resin, consisting of 1% crosslinked polystyrene functionalized with the TFA labile p-benzyloxybenzyl alcohol linker) . 50 - 95% TFA treatment generates free peptide acids. Fmoc D-amino acids on request.
