The choice of chemical modification applied to the structure of a peptide would be important for the improvement of pharmacological property of the peptide. Of course peptides are easier to synthesize and purify than whole proteins, but it is difficult to synthesize repeating, hydrophobic peptide sequence or modify side chain by conventional method. Modified peptides are also manipulated to substitute different amino acids or reorder amino acids from their native conformation to improve the specificity and efficacy of a therapeutic peptide. Molecular Hiving^® enables the company to easily modify the peptide sequence, especially complicated modification such a polysaccharide or sugar chain.
