Exploring Methods for Host Cell Protein Analysis

Biotherapeutics now represent a large proportion of therapeutics available on the market. The host systems often used to manufacture protein-based biotherapeutics can produce their own endogenous proteins, known as host cell proteins (HCPs), which can ultimately contaminate the product.

Download this list to learn about some of the most commonly used methods for HCP analysis, including:

• ELISA
  
• Western blot
• Proximity ligation assay
• Mass spectrometry
