Sulfosuccinimidyl Myristate Sodium (CAS 162823-01-0)

Sulfosuccinimidyl myristate sodium, registered under CAS number 162823-01-0, is a specialized chemical derivative used primarily in biochemical and biophysical research. This compound is a sulfo-N-hydroxysuccinimide ester of myristic acid, where the myristate component is a fourteen-carbon fatty acid linked through an ester bond to a sulfosuccinimidyl group. The addition of the sodium ion enhances its solubility in aqueous solutions, making it particularly useful in laboratory settings. The key functionality of sulfosuccinimidyl myristate sodium lies in its ability to act as a reagent for the covalent modification of proteins and other biomolecules. The sulfosuccinimidyl group is highly reactive towards nucleophilic groups, such as amines present on lysine residues or the N-termini of proteins, facilitating the stable attachment of the hydrophobic myristate group. This modification is extensively used in the study of protein-lipid interactions, membrane biology, and the anchoring of proteins onto cell membranes, enabling researchers to investigate how lipid modification affects protein localization, function, and interaction with cellular membranes. Such studies are crucial for understanding the complex dynamics of cellular membranes and the role of lipid modifications in cellular signaling and protein trafficking. This chemical thus provides a valuable tool for manipulating and studying the properties of proteins in a controlled and specific manner.
