Protein Lyophilization Service

Lyophilization (Freeze-drying) has been widely used in preparing therapeutic protein products in recent years because it can facilitate the storage and transportation of drugs. In order to facilitate the research development and production of drugs for the treatment of rare diseases, our company provides cryogenic freezing and vacuum drying services for liquid drugs, which can maintain the activity and stability of drugs for the treatment of rare diseases for a long time.

Introduction to Protein Lyophilization

Lyophilization is one of the most widely used drying techniques for improving drug stability. This flexible process depends on the ice sublimating from the frozen sample and then desorption under vacuum. Since the 1990s, commercial lyophilization for various pharmaceutical preparations has been fully developed. Because most protein products are prepared in aqueous solutions, lyophilization can solve the problem of their low stability and short half-life. The drugs commonly produced by lyophilization are mostly injections, most of which are antibiotics, circulatory organ drugs, central nervous drugs, and tumor drugs.

The Role of Lyophilized Protectant in Protecting Protein Drugs

There are many freezing stresses and drying stresses in the lyophilization process of protein, which often directly or indirectly lead to the loss of natural conformation of protein drugs, thus denaturing or inactivating. Therefore, even if lyophilization is adopted as a mild drying method, a suitable lyophilization protectant should be added to protect the stability of the protein.

Our Services
