Latest Patents

One of his latest patents is titled "Primer extension using modified nucleotides." This invention provides methods and compositions that reduce target-independent primer extension or enhance template-dependent primer extension. The applications of this invention extend beyond PCR to include nucleic acid sequencing, genotyping, and other methods that require target-dependent primer extension.

Another significant patent is "Method for detecting mutations using arrayed primer extension." This method involves attaching oligonucleotide primers to a substrate, which are complementary to a target nucleic acid sequence. The primers are grouped based on the expected first base to be added during primer extension. The process includes hybridizing a sample nucleic acid sequence that may contain a mutation, extending each oligonucleotide primer, and detecting any mutations by identifying the presence of a labeled ddNTP that does not match the expected base. This method can detect mutations in both mRNA and DNA, utilizing various labeling techniques.
