Latest Patents

Walsh's latest patents include the development of phosphoramidate-phosphodiester oligonucleotide chimeras. These novel chimeric phosphoramidate oligonucleotides are designed for use in primer-extension methods, such as DNA sequencing and nucleic acid amplification. The invention features both N3'-phosphoramidate linkages and phosphodiester linkages, allowing for enhanced primer extension methods. The chimeric oligonucleotide primer is annealed to a polynucleotide template, and after this process, it is extended by joining a nucleotide to the 3' end of the primer through a DNA polymerase catalyzed reaction. The invention also includes methods that utilize phosphoramidate linkage containing polynucleotide templates, enhancing the efficiency of primer extension across phosphoramidate linkages. Additionally, the compositions developed by Walsh incorporate divalent cations to increase binding affinity and stabilize phosphoramidate linkages against hydrolysis during high-temperature processes, such as PCR and cycle sequencing.
