【摘要】 随着人类基因组测序工作的完成,多态性遗传标记及其检测手段日益受到重视。基质辅助激光解吸/离子化飞行时间质谱作为一种高通量的单核苷酸多态性分型技术受到关注,它不仅可以分析单核苷酸多态性,还可以进行微测序、分析短串联重复序列。目前的分析方法有:引物延伸法、连接酶反应法、肽核酸法、侵入法等。更多还原

【Abstract】 With the development of genomics and the accomplishments of human genomic sequencing, polymorphic markers and their analytic approaches are more and more important, and much attention has been paid to the fact that the analysis of single nucleotide polymorphisms utilizing matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS) is a high-throughput approach. MALDI-TOF MS can also mini-sequence and genotype short tandem repeat. The approaches to analyzing single nucleotide polymorphisms are primer oligonucleotide base extension, ligase reaction, peptide nucleotide acid, invader assay, and so on.更多还原
