For professionals in pharmaceutical research and development, particularly those focusing on drug delivery systems, the precise selection of lipid components is critical. 1,2-Dipalmitoyl-sn-glycero-3-phospho-L-serine sodium salt (DPPS-NA), identified by CAS 145849-32-7, stands out as a vital anionic phospholipid widely utilized in the formulation of liposomes. As a reputable manufacturer and supplier, we aim to provide insights into why DPPS-NA is indispensable and how to source it effectively.

Liposomes, microscopic spherical vesicles composed of lipid bilayers, are a cornerstone of modern drug delivery. They offer a biocompatible and biodegradable platform for encapsulating a wide range of therapeutic agents, protecting them from degradation and enabling targeted delivery. The stability and release characteristics of liposomes are heavily influenced by their lipid composition, and anionic phospholipids like DPPS-NA play a crucial role in modulating these properties.

DPPS-NA, with its two palmitoyl chains and a negatively charged serine headgroup, imparts specific characteristics to the liposome structure. Its presence can influence membrane fluidity, charge distribution, and interactions with charged drug molecules or biological targets. Researchers often buy DPPS-NA to achieve desired liposome properties, such as improved stability in physiological conditions or specific targeting capabilities. For example, its anionic nature can be leveraged in conjunction with cationic lipids to form more complex, functionalized liposomes.

When embarking on research that requires liposome formulation, sourcing high-purity DPPS-NA is a non-negotiable step. A purity level of 99%, as offered by many reputable suppliers, ensures that experimental results are reliable and reproducible. This is especially important when scaling up from laboratory research to clinical trials. Pharmaceutical companies looking to purchase DPPS-NA are often seeking consistent batch-to-batch quality from their suppliers.

Procuring DPPS-NA from a trusted source, such as a leading manufacturer in China, can provide significant advantages. These include competitive pricing, reliable supply chains, and comprehensive documentation. Researchers should not hesitate to request quotes and compare offerings from various suppliers to secure the best value for their investment. Understanding the price per gram for different quantities is essential for budget planning.

In essence, DPPS-NA is more than just a lipid; it's a critical functional ingredient that empowers the creation of advanced liposomal drug delivery systems. For scientists and product formulators, ensuring a consistent supply of high-quality DPPS-NA is key to unlocking the full potential of liposome technology.
