This solution is primarily used in cell culture applications to enhance cell growth and viability. It serves as a supplement to provide essential nutrients, particularly glutamine, which is critical for protein synthesis and energy production in cells. The inclusion of L-propylamine helps stabilize the glutamine, preventing its degradation and ensuring a consistent supply for optimal cell metabolism. It is commonly employed in the cultivation of mammalian cells, especially in research focused on cancer, immunology, and regenerative medicine. Additionally, it supports the production of monoclonal antibodies and other biopharmaceuticals in industrial bioprocessing. Its 100× concentration allows for convenient dilution, minimizing handling and reducing the risk of contamination.
