Surveyor™ Nuclease-Based Genotyping of SNPs |
|
Surveyor™ nuclease, a single-strand-specific endonuclease that cleaves DNA at the 3' side of a base-mismatch site in both DNA strands, can be used for genotyping of SNPs by preparing two different types of a heteroduplex: one from mutant DNA fragments and the other from a mixture of wild-type and mutant fragments. We show an example of this technique and propose that it can be used with some advantages instead of RFLP analysis. |
