Select from our Collections of Generic or Focused Cancer Cell Lines

  • OmniPanel™, a genomically diverse collection of more than 500 cancer cell lines for drug response screening

  • XenoSelect™, a diverse oncogenic in vitro screening panel of over 150 well-validated cell lines, with associated Cell Line Derived Xenograft models ready for in vivo efficacy studies

  • RNAseq Panel, more than 170 in-house genomically characterized cell lines to correlate mutation status, copy number variation, and expression levels with drug response

  • PrimePanel™, a unique collection of cancer cell lines with each primary cell originating from one of our genetically defined HuPrime® Patient-Derived Xenograft (PDX) models

Our characterized cell line panels can be used in OmniScreen™, our global program of high throughput cell based screens for target expansion, lead finding, and lead optimization projects.

A Comprehensive Range of Functional Assays

CrownBio’s extensive tool sets to determine the biological functions of each target, and to help you take go/no go decisions, include a variety of functional assays such as:

  • High throughput cytotoxicity screening
  • In vitro drug combination studies
  • 3D clonogenic assays
  • 3D Tumor Growth Assays using PrimePanel cell lines
  • Target validation studies
  • Adhesion, migration, and invasion assays
  • Angiogenesis assays
  • Apoptosis studies
  • ADCC and CDC analyses
  • Cell cycle analysis
  • Pharmacodynamics/Pharmacokinetics analysis

Immuno-Oncology In Vitro Screening

Cancer immunotherapy is coming of age as a treatment paradigm, however, development of new immunotherapeutics still faces many challenges. Testing new immuno-oncology compounds in vitro, before moving to the in vivo setting, has proved challenging for many new drugs such as biological agents.

CrownBio offers a wide range of assays and platforms for in vitro testing of immuno-oncology agents, including core immunophenotyping, functional assays, and technologies for the regulation of the tumor microenvironment, allowing you to move with confidence to the next phase of drug development.
