We also provide a large number of peptide modifications as well as peptide synthesis for diagnostic and therapeutic applications. Bio-Synthesis specializes in both, liquid phase and solid phase fmoc peptide synthesis chemistry. We have a long standing record in preparing biologically active polypeptides including long, complex and hydrophobic peptides synthesized to your specifications. Custom Oligonucleotide Specialists As a pioneer in oligonucleotide synthesis, Bio-Synthesis has been pursuing the development of new oligonucleotide-based techniques that can produce compounds with superior binding affinity and chemical/biological stability. As such, Bio-Synthesis has introduced a third generation of nucleic acid analogs, Bridged Nucleic Acid (BNA). These are RNA analogues which can be synthesized and spiked with DNA or RNA in order to modify the formation of nucleic acid helices.
