Descripción general

Tween® 80 is a non-ionic detergent and surfactant, classified as an ester of sorbitan and oleic acid. It is a versatile compound commonly employed in various biological applications, including cell lysis, nuclei isolation, and cell fractionation. Additionally, Tween 80 finds use in stabilizing proteins and facilitating protein membrane studies. Its effectiveness stems from its membership in the polysorbate group, characterized by the combination of sorbitol and sorbitane oleic esters with polyethylene glycol chains. These structural features contribute to Tween 80′s emulsifying capabilities and a broad range of applications.

Aplicación

Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines.
TWEEN® 80 has been used in drug vehicle solution for specific injections in mice and rats.[1][2] It has been used for the determination of esterase activity in bacterial cells.[3]

Acciones bioquímicas o fisiológicas

TWEEN® 80 is a polysorbate surfactant which helps in stabilizing proteins and in protein membrane studies. It is regularly used for the extraction of membrane proteins and isolation of nuclei from cells.[4][5][6]

Questions

1–10 of 11 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

  5. Hello, Is there an expiration date or retest date for this product?

    1 answer

    1. This product is not assigned an expiration date. It is assigned a recommended retest date of approximately 4 years after the quality release date. A recommended retest date is the time during which the product is expected to remain within established stability specifications, provided that it has been stored under defined conditions. After the Retest Date, product samples should be examined to ensure that the product is still in compliance with the established specifications.

  6. Is Product P1754, TWEEN® 80, sterile?

    1 answer

    1. The product is not sterile. Autoclaving a solution of TWEEN 80 is generally not advised. Sterile filtration is more easily done if the liquid is warmed to about 40°C and alternate portions of hot distilled water and TWEEN 80 are poured through the 0.22 μm filter. The TWEEN 80 will blend and remain in solution.
