Kit for detecting mutant nucleic acid sequence associated with cancer
A recently granted patent (Publication Number: US11965212B2) discloses a kit designed for detecting mutant nucleic acid sequences associated with cancer. The kit includes oligonucleotide primer pairs and restriction enzymes, with the primers specifically targeting fragmentation sites absent in mutant sequences. Notably, the oligonucleotide primers are labeled with detectable moieties, such as fluorescent dyes, to enable visual identification of mutations.
Furthermore, the kit offers versatility by allowing different primer pairs to be labeled with distinct moieties, enhancing the detection process. The patent specifies that the mutant nucleic acid sequences may contain various mutations like insertions, deletions, substitutions, or translocations compared to wild-type sequences. Additionally, the kit targets a range of cancers including non-small cell lung cancer, breast cancer, colon cancer, ovarian cancer, hepatocellular cancer, and pancreatic cancer, broadening its applicability in cancer detection and research. The use of specific restriction enzymes like MnlI, MseI, EaeI, FatI, and HpyCH4VI further enhances the precision and accuracy of the detection process outlined in the patent.
