  • Publication number: 20240132946
    Abstract: In some embodiments, the present inventions relates generally to compositions, methods and kits for use in discriminating sequence variation between different alleles. More specifically, in some embodiments, the present invention provides for compositions, methods and kits for quantitating rare (e.g., mutant) allelic variants, such as SNPs, or nucleotide (NT) insertions or deletions, in samples comprising abundant (e.g., wild type) allelic variants with high specificity and selectivity. In particular, in some embodiments, the invention relates to a highly selective method for mutation detection referred to as competitive allele-specific TaqMan PCR (“cast-PCR”).

  • Publication number: 20220372578
    Abstract: Provided is an application of a miRNA fingerprint in the diagnosis and treatment of human bladder and urothelial carcinoma (comprising bladder cancer, renal pelvic carcinoma, ureter cancer, urinary outflow tract cancer, and the like). A plurality of fingerprints consisting of miRNAs can effectively distinguish a urine sample of bladder and urothelial carcinoma from a urine sample of non-bladder and urothelial carcinoma, and has high sensitivity and strong specificity. The fingerprints can be effectively used for the detection and the early diagnosis and screening of bladder and urothelial carcinoma and the screening of drugs for bladder and urothelial carcinoma.
