General description

Agar is a polysaccharide consisting of β- D-galactopyranosyl and 3,6-anhydro-α-L- galactopyranosyl units. Depending on the source agar exists as various substituted forms such as methyl and sulphate ether. It is a linear galactan polysaccharide isolated from the cell wall of Rhodophyceae class of seaweeds.

Application

Agar has been used:
  • as a component of solid N6 complete medium
  • in modified Murashige and Skoog (MS) medium for culturing germinating lentil and faba bean seeds and in the regeneration of transgenic cauliflower and broccoli explants
  • as a component of agar mixture to simulate a vascular phantom in carotid vessel

Biochem/physiol Actions

Agar exists in left-handed helical conformation and aggregation of hexagonal fibers leads to gel formation. The hydrophobicity of the disaccharides determines its gelling property and solubility. Agar is a major component of the microbial solid medium. It has applications in tissue engineering, pharmaceutics and in cell encapsulation.

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
