Host Cell Proteins (HCP) are critical quality attributes and must be monitored during the manufacturing processes by an adequate control strategy.

Protagen Protein Services (PPS) developed an approach for qualitative and quantitative control of HCPs applying shotgun LC-MS. This approach enables us to gain knowledge about HCP level, clusters and species and allows for risk assessment in HCP control.

In this webinar, experts from PPS will discuss the USP and DSP parameters of four different biopharmaceutical products, two different process variants, and one mock fermentation on the HCP pattern by shotgun LC-MS analysis.
