Residuals Testing for Bioprocess Validation

Sidebar Image


Process-related impurities are introduced into the manufacturing process of biopharmaceuticals at a variety of stages. These impurities may originate from upstream steps such as cell and culture growth or harvest, during downstream processes, or from the use of single-use technologies. Process-related impurities may include cell-derived impurities, buffer components, antibiotics, surfactants, anti-foaming agents, process enhancing agents, catalysts, or compounds that leach from contact materials.

Process-related impurities are typically present at low concentrations in complex matrices, making their detection and quantitation quite challenging. Demonstration of their effective removal is a key to validating the manufacturing process. Therefore, process validation studies require a broad set of testing capabilities and expertise.
