应用创造酶切位点法检测单碱基突变

应用引物错配技术结合单碱基突变位点而配合成一个酶切位点，使之成为可用PCR-RFLP方法分析的突变位点，是对单碱基突变位点进行基因型鉴定的有效而简捷的手段。本文以鸡胞外脂肪酸结合蛋白(Extracelluar fatty acid binding protein,EX-FABP)基因单碱基突变的基因型检测为例，探讨了应用创造酶切位点PCR（Created Restriction Site PCR,CRS-PCR）检测单碱基突变基因型的思路、方法和策略。 Abstract:Created Restriction Site PCR (CRS-PCR) is a simple and efficient method to identify SNP genotypes.One or more mismatch bases are used in a primer to create a restriction site by combining SNP site after PCR.The CRS-PCR products can be genotyped with a way the same as PCR-RFLP.In the study,Extracelluar fatty acid binding protein (EX-FABP)　gene was served as an example for establishing the CRS-PCR method.Strategy of CRS-PCR was also discussed.

The Establishment of Method for Identifying SNP Genotype by CRS-PCR

Created Restriction Site PCR (CRS-PCR) is a simple and efficient method to identify SNP genotypes. One or more mismatch bases are used in a primer to create a restriction site by combining SNP site after PCR. The CRS-PCR products can be genotyped with a way the same as PCR-RFLP. In the study, Extracellular fatty acid binding protein (EX-FABP) gene was served as an example for establishing the CRS-PCR method. Strategy of CRS-PCR was also discussed.
