Protocol to access unknown flanking DNA sequences using Wristwatch-PCR for genome-walking
Here we describe a protocol for wristwatch PCR, an approach based on wristwatch-like structure formed between walking primers to obtain unknown flanks. We specify the criteria for designing wristwatch primers and gene-specific primers. We detail how to set wristwatch primer permutations to obtain pe...

Sumario: | Here we describe a protocol for wristwatch PCR, an approach based on wristwatch-like structure formed between walking primers to obtain unknown flanks. We specify the criteria for designing wristwatch primers and gene-specific primers. We detail how to set wristwatch primer permutations to obtain personalized walking outcomes and improve walking efficiency. We describe experimental procedures for isolating a DNA of interest using three rounds of nested wristwatch PCR as well as the subsequent steps for DNA purification, cloning, and sequencing. For complete details on the use and execution of this protocol, please refer to Wang et al. (2022).(1) |
