Application


  • A ′conovenomic′ analysis of the milked venom from the mollusk-hunting cone snail Conus textile--the pharmacological importance of post-translational modifications.: This research underscores the critical role of post-translational modifications in the biological activity of peptides derived from cone snail venom, illustrating the potential for developing novel pharmacological agents using peptide synthesis techniques like those involving Fmoc-Asp(OtBu)-OH (Bergeron et al., 2013).

  • Parallel high-throughput accurate mass measurement using a nine-channel multiplexed electrospray liquid chromatography ultraviolet time-of-flight mass spectrometry system.: This paper discusses a breakthrough in mass spectrometry, highlighting a method for high-throughput analysis which could be critical for the characterization of complex peptide products synthesized using Fmoc-Asp(OtBu)-OH (Fang et al., 2003).
