General description

Sodium carbonate is usually referred to as soda ash. Solvay process uses sodium chloride and limestone to produce sodium carbonate.[1] Sodium carbonate enhances the pretreatment of rice straw and enhances delignification process.[2] Sodium carbonate finds its application in the extraction of bioactive metabolites like epoxyditerpenoids and alkaloids and removes acidic compounds from the extract.[3] Sodium carbonate induces the phase separation in salt induced phase separation extraction (SIPSE) method and enhances the plasma partitioning with acetonitrile.[4]

Application

Sodium carbonate has been used:
  • to stop α-glucosidase enzyme activity using the extract of Terminalia species[5]
  • as a component in carbonate/bicarbonate buffer for enzyme linked immunosorbent assay (ELISA)[6]
  • as a component in the growth medium for Synechocystis strains[7]

Biochem/physiol Actions

Buffer component, may be used for the removal of peripheral membrane proteins.

Questions

1–4 of 4 Questions  

  1. 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

  2. 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/449/386/product-dating-information-mk.pdf
