CRISPR/Cas9 gene editing platform

The CRISPR/Cas9 system is a cutting-edge gene editing technology that allows for precise and efficient editing of a cell's DNA. This revolutionary technology has made a significant impact in the world of drug discovery with its simplified editing capabilities and minimal off-target effects. Our global CRISPR licenses cover an integrated drug discovery platform for in vitro and in vivo efficacy studies, enabling you to model diseases using stable knockouts/knock-ins and test the efficacy of your drugs with confidence.

These services offer a comprehensive solution for cancer disease modeling. With an extensive collection of cancer cell lines and follow-up studies using tumor organoids, you can be confident in the reliability of your research results.


Customized features for your research needs:

  • Extensive Biobank of Models: Choose from hundreds of well characterized cell lines, PDX-derived organoids, and adult stem cell patient derived organoids:

  • Ready To Use: Off-the-shelf engineered cell line selection for an already available option. Choose a custom build, or bypass initial cell line generation with one of our XenoBase cell lines, complete with characterization and data selection

  • In Vivo Validation Services: Use our extensive database of complex 3D organoid models (OrganoidBase) to later validate your compounds in vivo

  • Vector Controls: Confirm your downstream results with our robust quality controls
  • Commercially Available Cell Lines: Representing multiple tissues, hundreds of cell types, and reporter genes
  • Ready to use lentiviruses: Integrating and non-integrating options (allowing requirement for only a biosafety level 2 [BSL-2] facility)
  • Endogenous Tags: Luciferase tag options

    • CRISPR Applications

    • Disease modeling: Capture disease relevance and patient population heterogeneity

      Viral host factor identification: Better understand the molecular mechanisms underlying viral entry, replication and pathogenicity

Predictive biomarker identification: Determine potential biomarkers of therapeutic response with companion diagnostics

Immunotherapy assessment: Utilize immune checkpoint inhibitor resistant models for compound validation

Bridging in vitro and in vivo: Ease your study transitions from in vitro studies with vivo validation

Gene modification for gain- or loss-of-function studies: Run a conclusive experiment that allows you to quickly validate or invalidate your gene target

Phenotypic assessment: Assess if a phenotype is specific to a particular protein or if a gene target provides the same phenotype in multiple cell types

Study Options

Accelerate your discoveries with our reliable CRISPR solutions. Our milestone-measured process ensures that data is provided at key intervals, overcoming any limitations prior to project advancement. Your project can be fully customizable to ensure seamless delivery. 


  • Gene Knockout and/or Gene Knock-in: Introduce your CRISPR components into cells via one of our several transfection methods: Lipofection, electroporation, nucleofection, or lentiviral transfection

  • Single Point Mutations: Screen for mutations that affect protein function, or add tags to endogenous proteins in cell lines. Studies include in vitro drug screenings, mechanism of action, and biological function.

  • Knockdowns: Reduce the expression of your gene with SiRNA and ShRNA transient and stable options

  • Knock-out cell pools: Initiate your test at lower cost with a cell pool. We use CRISPR transfection to express Cas9 and cell pool testing to confirm presence of Cas9

  • Biomarker analysis, genome sequencing, and validation: Conduct standalone in vitro and/or follow up with in vivo model validation services

  • Lead Screening and optimization: Option to use reporter/disease modeling cell lines or cell line derived xenograft models

  • Efficacy Testing: Leverage both 2D and 3D models to quantify efficacy across patients and compounds and predict in vivo response. Leverage high content imaging services to produce highly comprehensive morphology readouts
  • Ready to Use: Ready-to-transfect predesigned sgRNAs or use custom designed SgRNA and HDR template
