# Host Cell Protein (HCP) Testing Analysis Services Laboratory

## HCP Analysis: ensuring the Purity and Safety of Biologics

Ensuring the purity of finished products is essential to guarantee safety across all applications, from [monoclonal antibodies (mAbs)](http://Ensuring%20the%20purity%20of%20finished%20products%20is%20essential%20to%20guarantee%20safety%20across%20all%20applications,%20from%20monoclonal%20antibodies%20(mAbs)%20and%20recombinant%20proteins%20to%20vaccines.%20%20During%20production,%20host%20cell%20lines%20(such%20as%20CHO,%20E.%20coli,%20HEK,%20or%20yeast)%20inevitably%20release%20their%20own%20proteins,%20known%20as%20Host%20Cell%20Proteins%20(HCPs).%20Even%20at%20trace%20levels%20(ppm),%20these%20process-related%20impurities%20can%20present%20significant%20risks%20and%20must%20be%20rigorously%20monitored.) and [recombinant proteins](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization.md) to vaccines.

During production, host cell lines (such as CHO, *E. coli*, HEK, or yeast) inevitably release their own proteins, known as **Host Cell Proteins (HCPs)**. Even at trace levels (ppm), these process-related impurities can present significant risks and must be rigorously monitored.

**FILAB** supports pharmaceutical companies by offering complete HCP characterization strategies, compliant with the strict requirements of regulatory agencies (ICH Q6B)

### Is HCP testing essential for your process validation?

## HCP Analysis

 HCP analysis is not just a final check; it is a tool for process optimization. By analyzing samples at different purification stages (Downstream Processing - DSP), FILAB helps you:
Monitor **Clearance**: demonstrate the efficiency of your purification steps (Chromatography, Filtration)

Investigate failures (**[Troubleshooting](https://filab.fr/en/sectors-of-activity/health-pharmaceutical-cosmetics/laboratory-substance-troubleshooting.md)**): understand why a specific batch shows abnormal impurity levels

Ensure **reproducibility**: prove batch-to-batch consistency to health authorities

## Our FAQ

 What regulatory standards does FILAB follow for HCP analysis?
Our analyses are designed in accordance with[**ICH Q6B**](https://filab.fr/en/sectors-of-activity/biopharmaceutical/protein-characterization-ich-q6b-laboratory.md) guidelines (Specifications for Biotechnological Products. We operate under a quality system based on [**ISO 17025**](https://filab.fr/en/about-us/accreditations-en/laboratory-analysis-iso-17025.md) and **GMP** principles.

 What sample volume is required for an HCP analysis?
This depends on the protein concentration and the chosen method. Generally, a few milliliters or milligrams of active substance are sufficient. [Contact our technical sales team](https://filab.fr/en/contact-form.md) for a precise feasibility study.

 How to get a quote with FILAB?
