Why JITAI BIO

Core strengths

01

Precise molecular synthesis

Solid-phase and liquid-phase peptide synthesis plus fragment condensation run in parallel. Complex long chains, modified peptides, and combos can be scaled reliably.

02

Closed-loop QC

HPLC, LC-MS, amino-acid analysis, and endotoxin testing. Every lot ships with a COA / HPLC chromatogram.

03

From research to scale-up

From milligram custom work to hundred-gram supply, with traceable process parameters for later formulation and registration work.

04

Global delivery

Cold-chain and ambient shipping, with sterile water / acetic-water solvent systems, for research labs and API partners.

Platform

A complete peptide technology platform

From sequence to release, four production lines run as a closed loop for research-grade through scale-up delivery.

Solid-phase synthesis platform
SPPS Platform

Solid-phase synthesis platform

Automated peptide synthesizer cluster supporting Fmoc / Boc chemistry, side-chain modification, fatty-acid conjugation, and PEGylation.
