Abstract

A method for high-throughput screening for a well-characterized mutation at the APC locus was developed using stepped PCR primers, pooled product, and fluorescent single-strand conformation polymorphism (SSCP). Using a panel of two known normals, three known heterozygous mutants, and one known homozygous mutant, eight stepped PCR products were developed that showed the same mobility shift on a PE Biosystems 373A. Using this method, up to eight different samples can be pooled for same lane analysis.

摘要

利用阶梯式PCR引物、混合产物和荧光单链构象多态性(SSCP),开发了一种用于高通量筛选APC基因座特征明确突变的方法。使用一组两个已知的正常样本、三个已知的杂合突变体和一个已知的纯合突变体,开发了八个阶梯式PCR产物,它们在PE Biosystems 373A上显示出相同的迁移率变化。使用这种方法,最多可以将八个不同的样本混合进行同泳道分析。
