Synthesis of Peptide Nucleic Acids

The synthesis of PNA oligomers, or PNA oligomers, is a critical aspect of their utilization. While the synthesis is a little more challenging due to the preparation of monomers and their solubility, established protocols exist. Conventionally, PNA synthesis can be achieved using standard solid-phase peptide synthesis protocols for peptides. This involves using N-protected PNA monomers.作者：N Zhang·2010·被引用次数：45—The techniques described in this review represent a small snapshot of how PNA-basedapplicationscould be further developed in the area of diagnostics. Both Boc (tert-butyloxycarbonyl) chemistry and Fmoc (fluorenylmethyloxycarbonyl) chemistry are employed, with specific guidelines available for PNA synthesis by Boc chemistry and synthesis of PNA oligomers by Fmoc chemistry. Automated DNA synthesizers can also be adapted for PNA synthesis, offering a more streamlined approach. Researchers have developed convenient protocols for the use of various delivery systems, such as MPG-8 or PEP-3-nanoparticle technologies, to facilitate PNA and siRNA delivery into both adherent and suspension cells, expanding their applications significantly.
