実験手順

The protective peptide is built on 1.00 g (0.80 mmol) of H-Lys(Boc)-2-chlorotrityl resin using Fmoc-Val-OH, Fmoc-Lys(Boc)-OH and Palm-OSu. The resin is treated for 30 min with 8 ml of TFA 95% and the solution is instilled in 100 ml of Et2O. The precipitate is sucked off, washed and purified by prep. HPLC after drying. The substance is diluted in 30 ml of dioxan:water=4:6, treated overnight with 2.0 g of BioRad resin (acetate form), filtered, rotated and lyophilized.
