Live webinar 1 December
3 reasons why you should check the coverage of your HCP-ELISA

Attend this webinar to learn ELISA-MS™ coverage analysis can be used to
a. select the ELISA that best covers specific HCPs in your product or HCPs of concern for product stability and patient safety
b. find the reasons behind typical problems with your ELISA
– without a null cell line and with a low amount of antibody.

Focus on
Coverage analysis of ELISA

Our new HCP coverage analysis based on immunocapture with ELISA polyclonal antibodies followed by LC-MS/MS protein identification is a breakthrough in evaluation of ELISA HCP coverage. The analysis is performed on the native HCP antigens and provides a list of individual HCPs recognized by the ELISA antibodies.

Focus on
HCP analysis using mass spectrometry (LC-MS)

We offer a broad range of mass spectrometry based analyses of Host Cell Proteins that can be applied from the onset of your project and throughout the development phase. Apply the analysis on its own or in combination with ELISA assays for detailed analysis of process-related impurities in your biologic

Frequently asked questions

Which analyses should be included in biopharmaceutical protein analysis?

For approval by regulatory authorities, typically methods like intact mass, peptide mapping, N-terminal sequencing, and impurity analysis must be carried out to ensure proper documentation. This is both to verify the protein sequence, assess PTMs, evaluate the purity (and identify harmful protein residuals), as well as establish production consistency.

Where can I get more information about Host Cell Protein analysis by mass spectrometry?

A great place to start is a webinar. You can find on-demand webinars at

What makes Alphalyse experts in HCP analysis?

Since 2002 our protein analysis lab has conducted thousands of analysis projects. Our first article on the use of mass spectrometry for the characterization of proteins was published in 2008. Since then we have developed a unique method of analyzing HCPs using mass spectrometry, and we have now successfully completed more than 150 HCP customer projects.
