Provided herein are methods and compositions to detect MET exon 14 skipping using RT-PCR, and methods of treating individuals with MET exon 14 deleted cancers.

Detection of MET exon 14 deletions and associated therapies

Embodiments of the disclosure relate to isolated nucleic acid sequences, methods of use thereof, and workflows for detection of severalspecies in a sample, particularly in a food or environmental sample. Embodiments of the disclosure may also be used to detect one or more species or strains offrom each other, for examplemay be detected independently of otherspp. Some embodiments also describe a duplexed assay that can detect(formerly-),, and. Kits for detection ofare also described. In some embodiments, methods and kits of the disclosure may comprise a TAQMAN&#xae; assay. In some embodiments, 0.2-2 cfu ofspp. are detected using the compositions, methods and kits after a 24-28 hour enrichment period.

[object Object]

Described are compositions, methods and kits for detection and/or differential detection of serovars ofsubsp.serovar such as S. Heidelberg and S. Hadar in samples. Some embodiments relate to multiplex amplification based molecular assays.

Disclosed are methods and kits for the specific detection ofO157:H7 and notO55:H7 from samples such as: complex food matrices, water, beverages, fermentation broths, forensic & biological samples, and environmental samples including food processing and manufacturing surfaces. In some embodiments, a method of the disclosure comprises: hybridizing at least a first pair of polynucleotide primers to at least a first target polynucleotide sequence, hybridizing at least a second pair of polynucleotide primers to at least a second target polynucleotide sequence, amplifying the at least first and at least second target polynucleotide sequences, and detecting the first and second amplified target polynucleotide sequence products, wherein the detection of both the first amplified target polynucleotide sequence product and the second amplified target polynucleotide sequence product is indicative of the presence ofO157:H7 in a sample and notO55:H7.

Disclosed are primer and probe compositions, PCR assays, methods and kits for the specific detection ofO157:H7 and notO55:H7 from a variety of samples. In some embodiments, methods for specifically detectingO157:H7 comprise: hybridizing at least a first pair of polynucleotide primers to at least a first target polynucleotide sequence, hybridizing at least a second pair of polynucleotide primers to at least a second target polynucleotide sequence, amplifying said at least first and said at least second target polynucleotide sequences, and detecting said at least first and said at least second amplified target polynucleotide sequence products, wherein the detection of both the first amplified target polynucleotide sequence product and the second amplified target polynucleotide sequence product is indicative of the presence ofO157:H7 in a sample and notO55:H7.
