Methods for detecting various types of polymorphic nucleic acid sequences are provided herein. The detection methods are based upon nucleic acid amplification procedures and the ability to detect “large” deletions or insertions in an automated fashion. For example, a deletion or an insertion in a target nucleic acid sequence in a test sample, wherein the deletion or insertion is at least
8
or more consecutive nucleotides, can be detected according to the following steps:
a) contacting the test sample with amplification reagents and a set of amplification primers to form a reaction mixture wherein the set of amplification primers hybridize with the target nucleic acid sequence and a standard nucleic acid sequence in the test sample;
b) subjecting the reaction mixture to amplification conditions to form a target nucleic acid sequence amplification product and a standard nucleic acid amplification product;
c) hybridizing a first labeled probe to the target sequence amplification product and a second labeled probe to the standard nucleic acid sequence amplification product;
d) detecting signals from the first probe and the second probe; and
e) comparing the signals from the first and second labeled probes to determine the presence of the deletion or insertion in the target nucleic acid sequence in the test sample.
本文提供了检测各类多态核酸序列的方法。这些检测方法基于核酸扩增程序和自动检测 "大 "缺失或插入的能力。例如,检测样本中目标核酸序列的缺失或插入,其中缺失或插入至少为
8
或更多的连续核苷酸:
a) 将测试样本与扩增试剂和一组扩增引物接触,形成反应混合物,其中扩增引物与测试样本中的目标核酸序列和标准核酸序列杂交;
b) 将反应混合物置于扩增条件下,形成目标核酸序列扩增产物和标准核酸扩增产物;
c) 将第一标记探针与目标序列扩增产物杂交,将第二标记探针与标准核酸序列扩增产物杂交;
d) 检测来自第一探针和第二探针的信号;以及
e) 比较第一和第二标记探针的信号,以确定测试样本中是否存在目标核酸序列的缺失或插入。
