At PCI, we think lyophilization cycle advancement is not just a science, but an art; Each individual drug solution that arrives in to the laboratory provides exceptional difficulties, and the design of a cycle involves an understanding of personal chemistry, properties, and conversation to produce a top quality product or service in each and every cycle.
The ability to completely transform drug products into a dry powder without compromising their structural integrity is especially vital for preserving The steadiness and efficacy of biologic products, for instance vaccines, antibodies, and various protein-dependent therapies.
