Description

Description générale

A modified lysine derivative for the preparation of fluorogenically-labeled peptides by Fmoc SPPS ^[1]. The Mca group fluoresces at 405 nm when stimulated at 340 nm, and is most commonly used in conjunction with Dabcyl and 2,4-dinitrophenyl quenching groups. Recently, Fmoc-Lys(Mca)-OH has been used to prepare lanthanide-based luminescent proteins by native chemical ligation ^[2]. Lys(Mca) was found to be stable to HF cleavage conditions used to synthesize the thioester fragments needed for ligation.
