실험 절차

Fmoc-Lys (mtt)-Resin was stirred with a mixture of 1% trifluoroacetic acid (TFA) and 0.1% triisopropylsilane (TIS) in DCM at 0° C. for 30 min and then for one hour at room temperature. Then, the resin was washed with NMP and DCM, and dried in vacuum. 2.68 gr. of loaded resin were obtained. This resin was then swelled with 25 ml NMP in the Presence of 930 mg Biotin, 1.44 gr. O-benzotriazole-N,N,N′,N′-tetramethyl-uronium-hexafluophosphate (HBTU), 513 mg N-hydroxybenzotriazole (HOBt) and 1 ml of diisopropylethylamine (DIEA). The reaction was stirred for 4.5 hr. Then, the resin was washed with NMP and DCM, and dried in vacuum. 2.8 gr. of Fmoc-Lys(Biotin)-resin were obtained.
