HCP Detect™ For Host Cell Protein Detection & Monitoring

Residual host cell proteins (HCPs) is critical to drug safety, efficacy and regulatory qualification. Incomplete detection in biotherapeutics development can lead to product degradation, product instability and adverse immunogenic reactions in patients. As regulatory authorities recommend monitoring and removal guidelines, there's never been a better time for a more reliable solution.

IMPROVE YOUR RISK CONTROL STRATEGY

No other technique provides a more sensitive, specific and gel-free solution to detect, quantify and monitor low abundance host cell proteins (HCP) than ProteoCarta™ mass spectrometry-based platform (LC-MS/MS) and HCP Detect™.

What is HCP Detect™?

Caprion’s state-of-the-art ProteoCarta™ mass spectrometry-based platform along with our unique HCP Detect™ solution addresses the limitations of immunoassays for HCP detection, quantification and monitoring.

Our solution provides an orthogonal method for the identification and quantitation of all types of process samples through all phases of biologics and biosimilar manufacturing to improve your risk control strategy.

How does mass spectrometry (LC-MS/MS) compares with immunoassays (ELISA)?

Although immunoassays, such as ELISA remain the gold standard, the presence of low levels of HCP requires a more sensitive method of detection. Immunoassays often don’t have the resolution to separate and detect individual HCPs.

How Mass Spectrometry Host Cell Protein Detection, HCP Detect™ Works?

HCP Identification

Based on in-solution digestion followed by in-depth peptide analysis with LC-MS/MS.

  • Unbiased (label-free, gel-free)
  • High sensitivity, reproducibility
  • Extensive coverage using proprietary datamining tools paired to multiple protein search
  • Confident protein assignments and abundance
  • Simple conversion to a quantitative multiplexed assay

HCP Quantitation, Targeted MRM

Rapid confirmation and absolute quantitation of individual HCP using highly specific and sensitive multiplexed MRM panels (LC-MRM/MS).

  • 10 or more known HCPs in absolute quantitation, 100 or more in relative quantitation, all in one single assay
  • stable isotope labeled (SIL) peptides for internal standards
  • Precise and accurate results in ppm with precision report
  • Standard curves and QC samples included
