Technology ~Synthesis (Microwave)~

Seamless scale-up by our own microwave technology.

Technology ~Synthesis (STag-PS™)~

STag ; Chemical Tag for Peptide Synthesis

  • designed for efficient and cost-beneficial LPPS
  • enable Peptide Soluble in non-halogenated organic solvent
  • highly Compatible with SPPS Fmoc chemistry (Impurity Profiles are identical)
  • 80% less solvent usage than SPPS
  • Enable to monitor reactions

STag-PS ; Serial Peptides Synthesis system using Stag

Technology ~Novel LPPS~

LPPS using C-terminally Unprotected AAs
