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

Application

Sodium chloride has been used:

  • as a component of buffer solution to prepare the pH solutions for open-circuit potential and cyclic voltammetry
  • in the preparation of Bold’s basal medium (BBM)
  • as a component of transcription and annealing buffer[1]
  • to maintain osmotic balance and ensure the purity and stability of the isolated extracellular vesicles (EVs)[2]
  • as a buffer for the lamination of lateral flow strips in the fabrication of lateral flow devices

Biochem/physiol Actions

Sodium chloride helps to stimulate the stable induction of T-helper cell 17 (TH17) cells.

Features and Benefits

  • Suitable for molecular biology and biochecmial research
  • Free from DNase, RNase, NICKase and protease
  • Tested to confirm low levels of heavy metal contamination, ensuring suitability for various applications.
  • Tested for the presence of Anionic and Cationic traces

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
