Tackling CHO Contamination Risks

Advanced HCP Detection for Safer Therapeutics

In the high-stakes scene of biopharmaceutical development, even a single contamination event can derail years of progress, compromise patient safety, and incur staggering financial losses. For researchers working with Chinese Hamster Ovary or CHO cells, which is the backbone of therapeutic protein production.

Managing contamination risks is not just a technical challenge but a critical mission. We understand that the path to safer therapeutics begins with precision tools to detect and mitigate contaminants like host cell proteins (HCPs).

Let’s explore the hidden dangers of CHO contamination, the evolving science of HCP detection, and how tailored solutions are empowering scientists.

Why CHO contamination demands attention?

CHO cells are celebrated for their ability to produce complex biologics, from monoclonal antibodies to vaccines. Yet their widespread use in biomanufacturing makes them vulnerable to contamination. Viral pathogens, such as Cache Valley virus and Epizootic hemorrhagic disease virus, can infiltrate cultures and shut down production. Mycoplasma, a stealthy bacterial contaminant, can linger undetected, disrupting cell health and therapeutic integrity. Even non-viral contaminants like residual HCPs which are proteins from the host cell that linger in final drug products, pose many risks. These proteins can trigger immune responses or reduce drug efficacy, making their detection a regulatory and clinical priority.

The consequences of contamination extend beyond lost batches. Beyond the immediate financial toll (often exceeding tens of millions of dollars), these events can delay life-saving treatments and erode trust in biopharmaceutical brands. For researchers, the pressure to minimise risks while accelerating timelines has never been greater.

How to detect Host Cell Protein (HCP)?

Traditional methods for HCP detection, such as enzyme-linked immunosorbent assays (ELISAs), remain a cornerstone of quality control. These assays use immobilized antibodies to bind and quantify HCPs, offering a rapid, scalable solution. However, their reliance on pre-selected antibodies can miss low-abundance or novel HCPs, creating gaps in coverage.

Advances in mass spectrometry (MS) are closing these gaps. MS-based approaches provide a detailed, unbiased profile of HCPs, identifying even trace contaminants that evade traditional methods. By combining ELISA’s efficiency with MS’s precision, researchers gain a comprehensive understanding of contamination risks. Yet integrating these technologies requires expertise is a challenge Denovo Biolabs addresses through customized assay design.

What are we doing for it?

We recognise that no two bioprocesses are identical. Our approach to HCP detection begins with collaboration. By partnering with researchers early in development, we design assays that align with their unique cell lines, purification workflows, and regulatory goals.

  1. Custom ELISA Development :
    Our team engineers antibodies tailored to detect HCPs specific to your CHO strain, ensuring no contaminant goes unnoticed. This targeted strategy reduces false negatives and streamlines validation.
  2. Advanced Mass Spectrometry Integration :
    For complex biologics, we pair ELISA with MS to create a “dual-check” system. This hybrid method identifies rare HCPs and validates process consistency—critical for FDA submissions.
  3. Contamination Risk Mitigation :
    Beyond HCPs, we help labs address viral and mycoplasma risks. From viral clearance studies to mycoplasma detection protocols, our tools ensure robust safeguards at every production stage.

The Bottom Line

In an era where biologics represent 30% of the pharmaceutical pipeline, the stakes for contamination control have never been higher. Advanced HCP detection is not only about compliance, it is about ensuring every dose meets the highest standards of safety and efficacy.

By choosing Denovo, researchers gain more than a vendor; they gain a partner committed to turning contamination risks into manageable variables. Our custom solutions empower labs to accelerate discovery, reduce costs, and deliver therapeutics that clinicians and patients can trust.

Contamination control is a dynamic battlefield, but with innovations in HCP detection and a proactive approach to risk management, the biopharmaceutical industry is better equipped than ever to protect its innovations. And we are proud to stand at the forefront of this effort, turning cutting-edge science into practical, scalable solutions.
