The DURAClone RE CTC and PerFix CTC reagent system is the first ready-to-use solution for flow cytometry that enables identification and isolation of human circulating tumor cells from whole blood.

This new system delivers:

  • High specificity due to an expert-proven marker combination and staining protocol
  • High sensitivity through compatibility with up to 5 mL of whole blood
  • Easy data acquisition without the need for spillover correction
  • Less risk of error and variability by eliminating antibody pipetting and wash steps (only 1 spin-down step required)
  • High yield of intact single-cell DNA through mild preparation chemistry

For Research Use Only. Not for use in diagnostic procedures.


Expert Panels

  • Proven marker combination to detect small populations of normal and abnormal immature B cells
  • Open channels to add drop-in markers to modify for different research questions
  • Designed for assay precision and lot-to-lot consistency


  • Eliminate time spent in titrating different antibody lots
  • Avoid waste that comes from preparing cocktail master mix
  • Simplify inventory management


  • Unitized assays eliminate error prone pipetting steps
  • Includes lot matched tandem dyes for compensation controls for improved accuracy
  • Dry format maintains reagent performance better than liquid under stress conditions

Easy to Use

  • Ready to use assay with verified panel design
  • Includes sample preparation and staining procedure
  • Streamlined workflow, just add sample, incubate, wash and acquire
