Frequently Asked Questions

Common challenges include maintaining protein stability, preventing aggregation, ensuring optimal pH and osmolarity, managing viscosity for injectability, and addressing the complexities of scaling up production processes. To tackle these challenges, it is important to consider manufacturing and formulation conditions carefully, and use high-quality process chemicals and functional excipients.

Biopharmaceutical excipients are used to support the stability, performance, and manufacturability of biologics. They play a critical role in maintaining the stability and functionality of biomolecules such as monoclonal antibodies and other proteins, peptides, and nucleic acids throughout the manufacturing process, storage, and administration.

Common excipients for biomolecule formulations include: buffers and pH modifiers for optimizing process and formulation conditions; inorganic salts for tonicity adjustment; antioxidants to protect the biomolecule from oxidative degradation; protein stabilizers (such as sugars, polyols, and surfactants) to stabilize the biomolecule against mechanical and thermal stresses; viscosity modifiers that adjust the viscosity as required for processing and administration, and adjuvants that are used in vaccine applications to improve immune response.
