MALDI-TOF Mass Spectrometry

Major strengths of mass spectrometry analysis include the accuracy of the detection principle, automatic data storage as well as simplicity and flexibility of assay design making it a premier choice for targeted genotyping of sequence variations. 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, re-sequencing, and quantitative analysis for copy number variations and gene expression studies are given.
