Avance Biosciences developed and compared NGS and ddPCR-based potency assay platforms for a client’s LNP gene-editing drug product, screening candidate cell lines and dose ranges to establish a reproducible, cross-validated readout method.
Avance Biosciences developed a cell-based NGS assay to characterize on- and off-target gene-editing activity for a client’s LNP drug product, comparing editing at both loci across single-dose and repeated low-dose exposure to support its nonclinical characterization program.
This guide provides an in-depth look at GUIDE-Seq/iGuide, a key technique for assessing CRISPR-Cas9 on- and off-target effects in gene and cell therapy development. It explains how the method informs the selection of gRNAs, nucleases, and CRISPR conditions to maximize specificity and safety. Readers will also gain insights into the full workflow, from Cas9 cleavage to NGS analysis, supported by Avance Biosciences’ expertise as a licensed GUIDE-Seq service provider...
