Application

Agar is commonly employed in research for:
  • agar plates for microbiology, such as Tryptic soy broth or TSB Agar plates for bacterial cell culture
  • 50% Murashige-Skoog or MS medium (basal MS)for growing plant seedlings
  • micropropagation of Pistacia lentiscus or Lentisk, for shoot initiation

Features and Benefits

  • High-quality agar powder for general use in research
  • Suitable for microbiology applications to culture bacteria and other microorganisms
  • Suitable for plant cell culture for horticultural science and biotechnology
  • Easily prepare and autoclave for a solid or semi-solid media at 6 - 12g/L

Questions

1–3 of 3 Questions  
  1. What is the gel strength of agar A1296?

    1 answer
    1. The product information and specification sheet for this product do not specify an exact gel strength value. Details provided include recommended usage (6-12 g/L), gelling temperature (32-35°C), pH (7.0-7.5 at 1.5%), and ash content (2-5%), but a gel strength in g/cm² is not listed.

  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/418/501/product-dating-information-06-25-mk.pdf

  3. 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
