CometAssay® Control Cells

Select an Option to See Pricing

These cryopreserved cell preparations contain different levels of DNA damage to be used as controls when performing the comet assay. Select the appropriate set of control cells when performing either the alkaline or neutral comet assay.  Both sets are provided at 5 x 105 cells/ml.

Available Size(s): 10 Assays Catalog Number: 4257-010-CC Category:


A healthy control cell population (C0) is treated with a DNA damaging agent to increase the amount of damage in populations C1, C2 and C3, respectively. Etoposide is the damaging agent used for Alkaline Control Cells (CC0-CC3) and Bleomycin is the damaging agent used for Neutral Control Cells (NC0-NC3).


  • Provides a range of DNA damage for comparison with statistically distinct populations.
  • Allows for electrophoresis method to be standardized between individual users.
  • Standardized with Trevigen’s CometAssay® Electrophoresis System
  • Cell populations remain stable in liquid nitrogen for long term storage.
