Alphalyse scientist successfully defends PhD thesis

CONGRATULATIONS to Katrine Pilely who Tuesday successfully defended her PhD thesis at the University of Copenhagen. Under supervision of Professor Peter Garred, Katrine Pilely studied how cholesterol crystals activate the immune system. This happens through complement-mediated mechanisms, and therefore contribute to the pathophysiology of atherosclerosis. Katrine further showed how to inhibit the upstream cholesterol crystal-induced… Read whole story

Easy method for following specific HCPs through purification steps

See how Rikke Lund’s team helps remove host cell protein contaminants from recombinant protein. In this short video Rikke gives examples of customer results. The HCP analysis provides the customer with both identity and quantity of individual HCPs. This makes it possible to compare and identify differences of various production batches. In addition, the method is a… Read whole story

Document process-related residual protein in final drug substance

Standard analyses do not detect trace amounts of protein process additives, otherwise known as residual proteins. Examples include growth factors, Benzonase nuclease, Protein A, enzymes for site-specific PEGylation, etc. Instead you can now use a customized LC-MS assay. It will detect protein residuals of interest – in both your final drug substance and process samples…. Read whole story

2019 New Year Resolution: No more Western Blotting!

Yes, we are determined to wipe out Western Blotting as the standard HCP-ELISA coverage analysis. To meet customer demand, our HCP team is thus stepping up with yet another team-member; Katrine Pilely. Since new year, Katrine has taken part in the Alphalyse onboarding program and she is now ready to provide customers with useful information… Read whole story

Biologics Characterization Workshop – HCP quantification

“Generic ELISAs may underestimate Host Cell Protein content in your drug-product. Mass spectrometry is more accurate and sensitive than both generic and process-specific ELISAs, and much faster to set up than process-specific ELISAs. However, what really makes Mass spectrometry stand out is its ability to identify and quantify each specific Host Cell Protein.” These were… Read whole story
