Somatic DNA Mutation Analysis.

Abstract excerpt

Somatic mutations in patient tumor DNA samples can be readily detected based on mass spectrometry. The MassARRAY system is a high-throughput matrix-assisted laser desorption time-of-flight (MALDI) mass spectrometer for detection of nucleic acids. The technique is based on single-nucleotide base extension. A series of PCR assays amplify specific DNA regions of interest harboring mutations. A third primer is then...
