Host cell DNA services

RSSL can conduct a wide range of analyses to support the identification of in-process host cell DNA contamination in biopharmaceuticals.

 

 

 

As biopharmaceuticals are produced within living cells, impurities such as host cell DNA and host cell proteins (HCPs) may arise during the manufacturing process, these are derived from the production system. 

 

Both host cell DNA and proteins pose a risk to patient safety, due to potential oncogenicity, infectivity and immunomodulatory effects. As a result, regulatory agencies have stringent guidelines for safe levels which need to be met before approval.

Our techniques

 

We offer a range of techniques for the quantitation of host cell DNA, including:  

 

  • Method development and validation to ICH guidelines 
  • 2-D PAGE 
  • Real-Time Polymerase Chain Reaction (RT-PCR) 
  • High throughput host cell DNA analyses with the MagMAX™ Sample Preparation System 
  • Spectrophotometric DNA quantification with PicoGreen® dsDNA quantitation assay 

 

Our scientists are experts in the accurate and sensitive quantitation of host cell DNA impurities, whether encountered at the drug discovery stage or in production.
