Gxene Biotech（Gxene Biotech）has extensive experience in peptide synthesis research. We have mastered advanced technologies in peptide synthesis, modification, and purification, enabling our peptide synthesis services to be widely applied in various research fields, including disease diagnosis, drug development, and vaccine development. Our peptide synthesis services are mainly based on liquid-phase peptide synthesis and solid-phase peptide synthesis. Gxene Biotech can synthesize peptide sequences up to ~200 amino acids, and a variety of analytical items are available for customers to choose from. For peptide sequences of fewer than 30 amino acids, we can deliver them to customers in only 2–3 weeks, greatly saving customers' time costs.

Peptides have high specificity and efficacy and are well tolerated. Because many functional peptides participate in human physiological processes as neurotransmitters, ion channel ligands, hormones, growth factors, anti-infective agents, etc., they are receiving increasing attention in drug development. In addition to their use in vaccines and drug development, synthetic peptides can also be used to study antigen-antibody interactions or perform epitope mapping based on microarray technology platforms, providing a theoretical basis for vaccine design.

 

Peptide Synthesis Technologies:

 

–LPPS (Liquid-Phase Peptide Synthesis): suitable for the synthesis of relatively short peptides

–Large-scale SPPS (Solid-Phase Peptide Synthesis): suitable for synthesizing long and complex peptide sequences

–Microwave technology: effectively improves reaction efficiency and increases the yield of synthesized peptides
