General description

Sodium chloride, an essential nutrient, plays a critical role in biochemistry and molecular biology, making significant contributions to various biochemical applications. Within biological systems, it serves as a fundamental electrolyte, regulating osmotic pressure, pH balance, and electrical conductivity, all of which are essential for proper cellular function and vital physiological processes. Furthermore, sodium chloride plays a pivotal part in maintaining protein structure and promoting enzymatic activity, essential for stabilizing protein conformations and catalyzing biochemical reactions. Its role extends to the regulation of cellular homeostasis and the facilitation of ion and nutrient transport across cell membranes.It is an integral component of buffers like PBS and SSC, where it aids in various biochemical procedures, including the creation of density gradients and the fine-tuning of biological functions. Notably, sodium chloride is used to increase the ionic strength in buffers and culture media, impacting the ionic environment crucial for specific experiments and cell culture. Moreover, it is applied in DNA precipitation from samples containing SDS and the removal of small nucleic acid fragments during plasmid DNA preparations. Its utility extends to cell culture applications, where it plays a role in bacterial, yeast, and cell culture growth media.In molecular biology and cell culture, sodium chloride is an indispensable salt that finds its place in various aspects of research. It is a common constituent in cell culture media, lysis buffers, and protein storage solutions, contributing to the maintenance of optimal conditions for cell growth and experimentation. The sodium chloride used in these applications is of high purity, rigorously tested for impurities such as DNases, RNases, phosphatases, proteases, and trace metals, making it the ideal choice for molecular biology and biochemical research
