Peptide nucleic acid (PNA) antisense effects in Escherichia coli.
Antisense peptide nucleic acid (PNA) can be used to control cell growth, gene expression and growth phenotypes in the bacteria Escherichia coli. PNAs targeted to the RNA components of the ribosome can inhibit translation and cell growth, and PNAs targeted to mRNA can limit gene expression with gene and sequence specificity. In an E. coli cell extract, efficient inhibition is observed when using...
متن کاملPNA biosensors for nucleic acid detection.
Biosensor devices, based on the conversion of nucleic acid recognition reactions into useful electrical signals, offer considerable promise for DNA diagnostics. The unique hybridization properties of solution-phase PNA can be extrapolated onto transducer surfaces in connection with the design of remarkably specific DNA biosensors. This article reviews the development of PNA biosensors, and disc...
متن کاملPeptide nucleic acid microarrays.
A fast and economical procedure for the production of peptide nucleic acid (PNA) microarrays is presented. PNA oligomers are synthesized in a fully automatic manner in 96-well plates using standard Fmoc chemistry. Subsequently, the oligomers are released from the support and spotted onto glass or silicone slides, which were activated by succinimidyl ester. This process allows for a concomitant ...
متن کاملChiral peptide nucleic acid monomers (PNAM) with modified backbones.
Convenient high yielding syntheses of optically pure PNAMs comprising l- or d-serine, l-lysine and l-arginine units linked to thymine or Cbz-cytosine are described. Simple workup and inexpensive reagents are employed and free amino acids are used as coupling components.
متن کاملCellular Morphology and Immunologic Properties of Escherichia coli Treated With Antimicrobial Antisense Peptide Nucleic Acid
Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...
