Reading Notes on “I Offer Peptides to You”—Fluorescein Amine Is a Termination Agent in Solid-Phase Peptide Synthesis
Fluorescein amine has been shown to be an excellent terminating agent used in solid-phase peptide synthesis to block unreacted amino groups. A comparison with the efficiency of acetylation termination reveals that products generated by the fluorescein amine method are evaluated as superior in peptide analysis, dansyl-based N-terminal assays, and bioassays. Moreover, the fragments terminated with fluorescein amine are converted into non-fluorescent spiro-lactones during the deprotection step. These spiro-lactones exhibit stability under subsequent solid-phase reaction conditions and can be readily removed from the target peptide.
