Study: Comparison of impurity profiles – and problematic HCPs – in mAbs

Alphalyse used a unique mass spectrometry-based assay to analyze and compare HCPs in more than 50 mAbs, including 16 commercial mAbs like Humira and Gazyvaro. Join us December 2nd to hear about the study setup, analytical method, and the HCPs identified. And also learn which potentially problematic HCPs we found in several of the mAbs.

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.

HCP analysis

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

"We are very pleased with the work of Alphalyse, who provide us with high-quality tests of our recombinant products. Perhaps most importantly, we can ship them hundreds of samples at once and always receive the analytic results shortly after"
GTP Technology, FranceGrégori Gross - PhD, Bid Manager

"We really enjoy collaborating with Alphalyse as part of our optimization of manufacturing processes. Not only do we gain access to their hands, but we also get to pick their brains for mass spectrometry knowledge"
Y-mAbs Therapeutics Inc, USATorben Lund-Hansen - PhD, SVP, Head of Technical Operations

"Alphalyse´s HCP analysis saved us for development of an ELISA assay that may not have worked anyway. The HCP team provided very competent explanations of test results and was very open in discussing the method capabilities"
Statens Serum Institut, DenmarkMax Kristiansen - MSc, Special Consultant Assay Development

"Using the Alphalyse LC-MS/MS coverage method in HCP-ELISA selection, we estimate a savings of approximately $1M and, likely, one year of development time"
SAVARA Aps, DenmarkLars Skriver - Senior Science Officer

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 https://www.alphalyse.com/webinars/

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 was published in 2008. Since then we have developed the method, and havenow successfully completed more than 100 customer projects.
