Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Major strengths of mass spectrometry analysis include the accuracy of the detection principle and the automatic data storage, making it a premier choice for high-throughput single-nucleotide polymorphism genotyping. We explain the assay principle in detail and give step-by-step laboratory instructions. Finally, references point toward further use of mass spectrometry analysis for molecular haplotyping, pooled DNA analysis, re-sequencing, and gene expression studies.
