Description générale

Agar, also known as agar-agar, is one of the biochemical agents most used in microbiology field. It is obtained from red algae Rhodophyceae, is the most abundantly used gelling agent in culture media. Agar is polysaccharide complex, composed of 70% agarose and 30% agaropectin.

Application

Agar has been used:
  • to culture Staphylococcus aureus for phage infection studies[1]
  • as a supplement with NZCYM media for culturing Campylobacter coli strains for lysogeny screening[2]
  • as a basic media component to improve in vitro ovule and embryo culture methods of cross Chitalpa hybrids to facilitate the rescue of triploids[3]
  • in the culture media for Bdellovibrio spp. and Micavibrio spp. strains to check their susceptibility towards a variety of select agents[4]

Autres remarques

A purified agar from which the naturally occurring pigments, salts and miscellaneous matter has been reduced to a minimum.

Questions

1–3 of 3 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
