Sintesi di peptidi in fase liquida (LPPS)

Scalable LPPS for complex peptides and fragments—ideal for difficult sequences, long segments and high‑purity intermediates.

Long segments / macrocycles

Convergent fragment coupling reduces step count and aggregation risk.

Hydrophobic sequences

Solution‑phase conditions and solvent control improve solubility and kinetics.

Intermediates for conjugation

High‑purity fragments for payloads, linkers or SPPS‑LPPS hybrids.

CAPACITÀ

Capacità principali

We design sequence‑appropriate strategies (Fmoc/tBu) with orthogonal protections, optimized coupling/deprotection, and sequence‑specific additives to deliver high purity at scale.
