Residuals Testing for Bioprocess Validation

Sidebar Image

BioProcess Residuals Vial MachineProcess-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. This can impact critical quality parameters and product safety by adversely modifying proteinaceous materials. 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.
