Fmoc固相多肽合成中Fmoc保护的赖氨酸Lys
Fmoc-Lys(Boc)-OH is a monoclonal antibody that reacts with lysine residues. It is synthesized by reacting a solid phase support with an aliphatic hydrocarbon. The reactive functional group on the hydrocarbon terminates in an amine and forms an amide linkage to the amino terminus of the peptide. The hydroxyl terminus of the peptide is then reacted with a trifluoroacetic acid (TFA) ester of lysine in the presence of base. This reaction produces a TFA salt of Fmoc-Lys(Boc)-OH, which can be purified by high salt precipitation or reversed to produce Fmoc-Lys(Boc)-OH by treatment with base. Fmoc-Lys(Boc)-OH has been used as a reagent for chemical conjugation to fluorophores and other molecules such as biotin, avidin, strept
