Quality Controls

Biologics are a very complex class of drug products due to the fact that biological molecules are inherently more complex, often not easily characterized, and the manufacturing process is more complex. Moreover, most biologics are made in cell culture and, therefore, these products are more likely to be contaminated with foreign agents such as viruses, mycoplasma and other transmittable pathogens. Control of product quality depends on the use of selected raw materials and careful adherence to strict manufacturing processes. Quality control procedures often include: prevention of accidental contamination, inactivation/removal. Due to the complex molecular structure of biological drugs, functional activity assays are often required to identify which structures are more or less potent. BOC Sciences provides comprehensive analytical and microbiological quality control services during all drug development projects.
