application

Locust bean gum (LBG, galactomannan polysaccharide) from Ceratonia siliqua seeds may be used as a substrate to help identify, differentiate and characterize mannanase(s), such as the β-Mannanases (EC 3.2.1.78). LBG may be used in the development of drug delivery devices. LBG may be used to study its properties as a protective agent on both eucalyptus and microcrystalline cellulose destruction of crystallinity by ball milling. LBG may be used to study its properties as a food additive that reduces spoilage caused by Aspergillus flavus. LBG may be used as a starting material for the organic synthesis of hyperbranched N-glycan core structures.

Other Notes

Believed to be a straight chain polymer of mannose with one galactose branch on every fourth mannose and a M.W. of approx. 310 kDa.

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.

  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
