PEPTIDES, OLIGONUCLEOTIDES AND PROTEINS
All the advantages of speed, purity and biological activity, only previously possible with much smaller peptides, are retained.
Peptides & Proteins
It is now possible to chemically synthesise proteins up to 170 residues in length. Our technology delivers high purity biological active products.
