Peptide Nucleic Acid Probe

Peptide nucleic acids (PNAs), as a kind of synthetic nucleic acid analogs, have proved to be of powerful use in molecular biology procedures and diagnostic analyses. In this respect, peptide nucleic acid probe has attracted a lot of attention because of its high sensitivity and specificity. Here, BOC Sciences, as an expert in nucleic acids, is very good at capturing the relevant research hotspots in the field of oligonucleotides and providing custom synthesis services for customers in need of PNA probe development.

Peptide nucleic acid (PNA) is a synthetic polymer similar to DNA or RNA.The backbone of PNA is built up from repeating N-(2-aminoethyl)-glycine units through peptide bonds (amide bonds). In the PNA molecule, various purine and pyrimidine bases are fused to the N of the glycine portion of the backbone through an acetyl structure.
