METHODS OF PEPTIDE SYNTHESIS
We can provide peptide synthesis from mg to kg of high-quality compound synthesis, such as synthesis of APl intermediates, reference

compounds, metabolites, and impurities expansion to non-GLP drug substances, as well as the development and synthesis of PROTAC drug molecules.

Main Methods:

1. Solid-phase peptide synthesis is used to prepare biologically active peptides, including long peptides, difficult peptides, and hydrophobic peptides.

2. Biosynthesis provides different types of peptide modifications and customized peptides for diagnostic and therapeutic applications.

SERVICE CONTENT OF OUR PEPTIDE SYNTHESIS
Free peptide consultation and design
Custom peptides according to your requirements such as ultra-long peptide.
Peptide modification
Mass spectrometry and HPLC chromatogram confirm purity and characteristics
Provided as a lyophilized powder

QUALITY CONTROL OF OUR CUSTOM PEPTIDE SYNTHESIS
After peptide synthetics, each type of peptide synthesized is routinely analyzed by LC-MS, MALD-MSor HPLC to confirm the quality of the customized peptide.

Mass spectrometry

All peptides were analyzed by MALDl-MS to determine the molecular weight of the synthetic peptides.

High-performance liquid chromatography

MALDI is an excellent method to determine the presence of the desired product but it is not sufficient to determine purity. Therefore, all non-crude peptides must be analyzed by reversed-phase HPLC(RP-HPLC) to determine the purity. Other QC analyses can be performed, such as amino acid analysis, NMR, CE, and peptide content determination to confirm the quality of customized peptides.

Other quality control (optional)

Chromatography (HPLC,TLC,GC，IC)

Chromatography combined with mass spectrometry (LC-MS/ESI)Metal analysis(AAS, ICP，ICP-MS)

Titration (acid-base titration, Karl Fischer titration)

Spectroscopy (Uv-Vis, IR, NMR)

Elemental analysis

Amino acid analysis

Peptide sequencing
