Abstract
Peptide nucleic acid (PNA) is an oligonucleotide mimic that recognizes and binds to nucleic acids. The strong binding affinity of PNA to mRNA coupled with its high sequence specificity enable antisense PNA to selectively inhibit (i.e., knockdown) the protein synthesis of a target gene. This novel technology provides a powerful tool for Campylobacter studies because molecular techniques have been relatively less well-developed for this bacterium as compared to other pathogens, such as Escherichia coli and Salmonella. This chapter describes a protocol for PNA-mediated antisense inhibition of gene expression in Campylobacter jejuni.
