Stability of Biologic Compounds

Biologic compounds like proteins, enzymes, vaccines, and antibodies are often unstable in liquid form. They can degrade over time due to chemical reactions, temperature fluctuations, or microbial growth, leading to reduced efficacy. Who Experiences This: Pharmaceutical Companies: Developing injectable drugs, vaccines, and biologics. Biotech Firms: Working on innovative therapies involving biologics. Academic and Clinical Researchers: Handling sensitive biological samples. How Lyophilization Resolves It: By removing water through freeze-drying, lyophilization stabilizes these compounds, preserving their structure and activity over extended periods.
