A PCR-Induced Mutagenesis-Restriction Fragment Length Polymorphism Method for the Detection of CRISPR-Induced Indels.
As CRISPR-based technologies are widely used for knocking out genes in cell lines and organisms, there is a need for the development of reliable, cost-effective, and fast methods that identify fully mutated clones. In this context, we present a novel strategy named PCR-induced mutagenesis-restriction fragment length polymorphism (PIM-RFLP), which is based on the well-documented robustness and simplicity of the classical PCR-RFLP approach. PIM-RFLP allows the assessment of the editing efficiency in pools of edited cells and the effective identification of fully mutated single-cell clones. It is based on the creation by mutagenic PCR of a restriction enzyme degenerate cleavage site in the PCR product of the wild-type allele, which can then be distinguished from the indel-containing alleles following the standard RFLP procedure. PIM-RFLP is highly accessible, can be executed in a single day, and appears to outperform Sanger sequencing deconvolution algorithms in the detection of fully mutated clones.

期刊介绍:
In recognition of this extraordinary scientific and technological era, Mary Ann Liebert, Inc., publishers recently announced the creation of The CRISPR Journal -- an international, multidisciplinary peer-reviewed journal publishing outstanding research on the myriad applications and underlying technology of CRISPR.
Debuting in 2018, The CRISPR Journal will be published online and in print with flexible open access options, providing a high-profile venue for groundbreaking research, as well as lively and provocative commentary, analysis, and debate. The CRISPR Journal adds an exciting and dynamic component to the Mary Ann Liebert, Inc. portfolio, which includes GEN (Genetic Engineering & Biotechnology News) and more than 80 leading peer-reviewed journals.
