Peptide-Synthesis Services Peptides-linear chains of amino acids-are the building blocks of nature. Understanding their action figures prominently in recent advances in many fields, particularly immunology. Such insight, for example, allows investigators to elucidate the details of antigen-antibody interactions of the human immune system.

VERSATILE: Services at Richmond, VA.-based Commonwealth Biotechnologies include peptide and DNA synthesis.
Because scientists aren't able to extract sufficient quantities of peptides from natural sources for their experiments, a growing number of companies are custom-manufacturing peptides for research. Synthetic peptides are used for a variety of molecular biological applications, including monoclonal or polyclonal antibodies for immunological research, peptidomemetics, and the testing of prospective drugs in clinical trials. Researchers generally target a specific amino acid sequence of the protein they're working on and order that sequence in quantities ranging from a few milligrams to many grams, depending on the project.
