Abstract excerpt
Allelic ratio of an SNP has been used for prenatal diagnosis of fetal trisomy 21 by MALDI-TOF mass spectrometry (MS). Because MALDI-TOF MS is challenging in quantification performance, pyrosequencing was proposed to replace MS by better quantification of allelic ratios. To achieve a simple and ra...
