Executive Industry Relevance

Unbiased identification of functionally relevant genomic elements is a critical inflection point in early drug discovery, directly impacting target validation and mechanistic de-risking. The InSET protocol enables genome-wide mapping of lentiviral integration sites, revealing novel exons and regulatory elements beyond annotated regions. This capability strengthens predictive confidence in target selection and supports risk-adjusted portfolio advancement.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables systematic interrogation of uncharacterized genomic regions for functional relevance.
• Supports biological de-risking by uncovering novel exons in both coding and non-coding RNAs.
• Facilitates robust target validation by linking integration site abundance to phenotypic outcomes.
• Improves predictive confidence for downstream target nomination and triage.

Screening & Assay Development

• Prepares validated insertional mutagenesis libraries for high-throughput phenotypic screening.
• Standardizes detection of integration sites using next-generation sequencing for quantitative outputs.
