RNA酶保护试验((RNaseProtectionAssay,RPA)简介
RNA酶保护试验((RNase Protection Assay,RPA)是通过液相杂交的方式,用反义RNA探针与样品杂交，以检测RNA表达的技术。1。原理：双链RNA（杂交的）能够抵抗RNA酶的降解。2。应用：检测RNA表达3。与Northern杂交和RT-PCR比较，RPA有以下几个优点：1． 检测灵敏度比Northern杂交高。由于Northern杂交步骤中转膜和洗膜都将造成样品和探针的损失，使灵敏度下降，而RPA将所有杂交体系进行电泳，故损失小，提高了灵敏度。2． 由于PCR扩增过程中效率不均一和反应“平台”问题，基于PCR产物量进行分析所得数据的可靠性将下降，而RPA没有扩增过程，因此，分析的数据真实性较高。3． 由于与反义RNA探针杂交的样品RNA仅为该RNA分子的部分片段，因此，部分降解的RNA样品仍可进行分析。4． 步骤较少，耗时短。与Northern杂交相比，省去了转膜和洗膜的过程。5． RNA-RNA杂交体稳......阅读全文
