摘要:
Fast and highly accurate mass spectrometry-based processes for detecting a particular nucleic acid sequence in a biological sample are provided. Depending on the sequence to be detected, the processes can be used, for example, to diagnose a genetic disease or chromosomal abnormality; a predisposition to a disease or condition, infection by a pathogenic organism, or for determining identity or heredity.
摘要:
Processes and methods for creating a database of genomic samples from healthy human donors, methods that use the database to identify and correlate polymorphic genetic markers and other markers with diseases and conditions are provided.

摘要:
A method for detecting methylated nucleotides within a nucleic acid sample is provided. The method includes the steps of splitting a nucleic acid sample into separate reaction vessels; contacting nucleic acid in one reaction vessel with bisulfite; amplifying the nucleic acid in each reaction vessel; cleaving the nucleic acids in each reaction vessel to produce fragments thereof; and obtaining a mass spectrum of the resulting fragments from one reaction vessel and another mass spectrum of the resulting fragments from another reaction vessel.
摘要:
Provided are methods for detecting a target nucleic acid in a biological sample using RNA amplification. In an embodiment, provided is a method that comprises (a) amplifying a target nucleic acid, or portion thereof, using a primer comprising a sequence that is complementary to a polynucleotide sequence in the target nucleic acid, or a complement thereof, and a sequence that encodes an RNA polymerase promoter; (b) synthesizing RNA using an RNA polymerase that recognizes the promoter; and (c) detecting the presence or absence of the resulting RNA using mass spectrometry thereby detecting the presence or absence of the target nucleic acid in the biological sample.
