Targeted genome editing using CRISPR-Cas, ZFNs, or TALENs enables precise gene function studies but often produces point mutations or insertions or deletions (indels) that are difficult to detect by conventional PCR. We developed a parallel qPCR assay with an iGenotype index for simple, reliable genotyping. iGenotype values (1, 0, -1) remained constant across allele-specific primers. qPCR data can be analyzed via an R program, enabling large-scale or automated genotyping. For complete details on the use and execution of this protocol, please refer to Fu et al.1.
