Abstract excerpt
A method for typing single nucleotide polymorphisms (SNPs) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is described, in which a mass-tagged dideoxynucleoside triphosphate is employed in a primer extension reaction in place of an unmodified dideoxynucleoside triphosphate (ddNTP). The increased mass difference due to the presence of the mass-tag greatly facilitates...
