Allgemeine Beschreibung

Glucan is a natural polysaccharide.[1] They are carbohydrates forming structural components, which is found in the cell walls of yeast, fungi, seaweed and cereals.[2]

Anwendung

Glucan from baker′s yeast (S. cerevisiae) has been used:
  • for immune stimulation[3]
  • to stimulate mRNA expression of a sigma class glutathione S-transferase (GST) in hemocytes[4]
  • to study its effects in rainbow trout intestinal epithelial cell line (RTgutGC)[5]

Biochem./physiol. Wirkung

Glucan enhances anti-infectious immunity, prevents cancer growth, lowers stress and reduces cholesterol level. It has immunostimulatory property.[2] It maintains blood sugar level and rejuvenates skin.[1]

Angaben zur Herstellung

Prepared by the method of Bacon, et al.[6]

β-glucan is a potent inducer of epigenetic and functional reprogramming of innate immune cells, a process called "trained immunity," resulting in an enhanced host response against secondary infections. We investigate whether β-glucan exposure confers protection against pulmonary Mycobacterium tuberculosis (Mtb)

In invertebrates, the prophenoloxidase (proPO) pathway is involved in the phenol-like antioxidant production against invading pathogens. Overproduction of melanin and phenolic substances leads to the disruption of hemocytes (own host cells); therefore, there is a prerequisite to regulate the antioxidant

The purple sea urchin, Strongylocentrotus purpuratus, possesses a sophisticated innate immune system that responds to microbes effectively by swift expression of the highly diverse Sp185/333 gene family. The Sp185/333 proteins are predicted to have anti-pathogen functions based on inducible gene

Questions

1–3 of 3 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/449/386/product-dating-information-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

  3. What is the solubility of the product?

    1 answer

    1. The solubility of this product can be found on the lot specific Certificate of Analysis. When dissolved in water at a concentration of 9.80 - 10.20 mg/mL, the product forms a turbid solution with visible insoluble particulates, and the solution color ranges from colorless to light yellow.
