30 min webinar Learnings from 350+ projects

Moving LC-MS analysis into a GMP environment

Across the industry, it has been a challenge to achieve Host Cell Protein analysis by LC-MS that complies with GMP due to the complexity of the sample preparation and data analysis, the sophistication of high-end mass spectrometers, and the lack of reproducibility of the complete workflow.

Watch this 30-minute webinar to find out:

  • How robust and reproducible is impurity profiling ​​​​​​​by mass spectrometry?
  • Is it possible to transfer the method to a GMP environment?
  • Which parameters should be tracked in the process?

Show me how you qualify MS data >>
  • This field is for validation purposes and should be left unchanged.

About this broadcast:

You probably already know that…

… for new biologics under development, validated HCP impurity assays are required for the GMP release test to show product purity.


Generic HCP-ELISAs often do not have sufficient coverage of the manufacturing process, and therefore, you would develop a process-specific ELISA.

But in some cases, this is not possible – e.g., for complex gene therapies consisting of proteins from several organisms.

Instead, many companies use Mass Spectrometry (MS) as an orthogonal method to ELISA

– especially since MS can identify and even quantify impurities at an individual level.

But is mass spectrometry available under GMP?

At this point, no one has established a robust LC-MS method for Host Cell Protein characterization that complies with GMP. It has been challenging due to

  • the complex sample preparation and data processing,
  • the sophisticated high-end mass spectrometers,
  • and the lack of reproducibility of the complete workflow.

So, how does Alphalyse address the challenges with variability?

Alphalyse scientists developed a robust and automated workflow based on data-independent and data-dependent mass spectrometry, along with intact proteins as internal standards for quantification and workflow optimization.

For the past three years, we have investigated the robustness and reproducibility of the method in more than 350+ projects.

The projects include different expression systems (e.g., CHO, E. coli, HEK, adenovirus), types of biologic (e.g., mAbs, recombinant proteins, vaccines, and gene & cell therapy products), and complexity of samples (e.g., from early process samples to final purified drug substances).

Common for all projects is that we used the same set of 7 standard proteins as internal standards. Therefore, we can now evaluate different parameters of importance for method validation and transfer the method to a GMP environment.

In this 30 minute webinar with Thomas Kofoed, Co-founder of Alphalyse, you will get:

Attend this webinar if:

  • You manage a biologic’s development and want to minimize risk, cost, and development time.
  • You are a technical specialist and struggle with inconsistent commercial HCP-ELISA kits.
  • You wish to quickly reduce the overall level and remove specific HCPs in few efficient purification steps.
  • You work with an uncommon expression organism that does not yet have a suitable ELISA.

Or want to brush up on the newest technologies for Host Cell Protein analysis and how to achieve a GMP compliant LC-MS method.
