Monitoring Impurities in Biologics

The complexity of biotherapeutic products and their manufacturing processes can yield a variety of impurities, which must be monitored and controlled to minimize safety concerns and ensure product quality.

These impurities can be broadly grouped into two categories: 1) product-related impurities, such as precursors, aggregates and degradation products, and 2) process-related impurities, such as host cell DNA, host cell protein, and particulates.
