Horizon's standard CDC assay services

Pick and choose cells from the OncoSignature™ panel during a consultation with our scientists, who can help guide you to the cell panel that best suits your needs.

Standard base project: 

  • 2 compounds per cell line (control IgG included)
  • Rituximab in Raji cells as an assay control

Standard CDC assay read-outs 

  • Part 1: percentage of calcein retention per cell line
  • Part 2: percentage cell lysis by fluorescence of released calcein per compound/cell line
    •  Assay run in quadruplicate
    • 9 point dose response (8 dilutions plus vehicle)
    • 3 or 4-fold dilution range

Our cloud-based data report includes:

  • Cell quality control metrics
  • Assay performance QC - Raji + Rituximab
  • Results summary
    •  Cell growth characteristics 
    • Calcein retention assessment
    • CDC assay
  • EC50 values and annotated readout
  • Raw Data and Metadata


Service description Number of suitable compounds Catalog Number
