Description

"A modified lysine derivative for the preparation of fluorogenically-labeled peptides by Fmoc chemistry [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.The product number for this product was previously 04-12-1233.To obtain a certificate of analysis (CoA) of a lot that begins with the letter ""A"", please select the option in the right hand menu ""Request a COA for Lot#s starting with A""."
