Non-ionic detergent used for immunoprecipitation and for the solubilization of membrane-bound proteins (aggregation number: 58; conductivity: <50 µmhos; CMC: 12 µM; HLB number: 15). Supplied as a 10% (W/W) solution of PROTEIN GRADE TWEEN 80 detergent.

Application


  • Performance of β-carotene-loaded nanostructured lipid carriers under dynamic in vitro digestion system: Influence of the emulsifier type.: This paper discusses the performance of β-carotene-loaded nanostructured lipid carriers, where TWEEN 80 is utilized as an emulsifier. The study highlights its impact on the stability and bioaccessibility of β-carotene during digestion, offering valuable insights for food science and nutraceuticals applications (Lüdtke FL et al., 2024).

  • Fabrication and characterization of transdermal delivery of ribociclib nanoemulgel in breast cancer treatment.: This study explores the use of TWEEN 80 in developing a transdermal nanoemulgel for the delivery of ribociclib, enhancing its therapeutic efficacy against breast cancer. The work focuses on innovative drug delivery systems that improve patient compliance and drug stability (Makeen HA et al., 2024).

  • A novel antifungal nanoemulsion based on reuterin-assisted synergistic essential oils: Preparation and in vitro/in vivo characterization.: Here, TWEEN 80 is used to create a potent antifungal nanoemulsion, incorporating reuterin and essential oils. The study emphasizes the potential of nanoemulsions to significantly enhance the antifungal activity of natural compounds, promising applications in food preservation and safety (Nikkhah M et al., 2024).

  • Development and characterization of edible and active coating based on xanthan gum nanoemulsion incorporating betel leaf extract for fresh produce preservation.: This investigation uses TWEEN 80 in a xanthan gum-based nanoemulsion, integrating betel leaf extract for the preservation of fresh produce. It highlights the role of such nanoemulsions in extending the shelf life of perishable foods, with significant implications for the food industry (Aayush K et al., 2024).

Questions

1–2 of 2 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
