Abstract excerpt
Matrix-associated laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is a tool currently under investigation for use in prenatal detection of abnormalities in chromosome number, such as trisomy 21. Because of its ability to detect extremely small differences in mass, even to the level of a single nucleotide difference, this method can be applied to the detection of single-nucleotide...
