Guide Select™

Screening assay

SeQure Dx's Guide Select is a biochemical screening assay based on the ONE-seq™ platform that enables variant-aware, off-target risk assessment for multiple guide RNAs in parallel. Guide Select enables you to de-risk development of your cell and gene therapy at an early stage by identifying potential off-target effects with high sensitivity and precision. This data-driven approach helps optimize guide RNA selection and streamline the development process, saving time and resources while supporting efficient therapeutic development.

Multiplexed off-target assessment assay designed for screening multiple guide RNAs in parallel. Variant-aware searching within a limited search space enables high-powered, low-cost, surface-level risk assessment for program prioritization and guide RNA selection.

In silico + biochemical evaluation

  • Low cost per guide
  • Screen high similarity off-targets
  • Population-scale variant assessment

Informed guide RNA selection

  • Evaluate multiple guides
  • Reduce program risk through early profiling and selection
