FAQ Custom Peptide Synthesis

Peptides, which are short chains of amino acids linked by peptide bonds, have a variety of biological functions, such as, anti-thrombosis, anti-hypertension, anti-microbial, anti-tumor and anti-oxidation, immune-regulation, and cholesterol-lowering effects. Peptides have been widely used in functional analysis, antibody research, vaccine research, and especially the field of drug research and development.

MedChemExpress (MCE) offers a comprehensive collection of high quality peptides including peptide inhibitors, β-amyloids, therapeutic peptides and amino acid derivatives to clients in pharmaceutical and academic institutions all over the world. Unlimited Custom Peptide Service is also available to help researchers propel their projects.
