Descrizione generale

La tecnologia Redi-Dri™ previene la formazione di aggregati e la necessità di ricorrere a procedure complicate per preservare le caratteristiche di scorrevolezza dei vostri sali. Mantenere asciutti i vostri sali migliora i vostri risultati fornendo misurazioni accurate e sali e tamponi più facili da utilizzare. Piuttosto che essiccare i vostri sali in forno o in essiccatore, o romperne gli agglomerati manualmente, Redi-Dri™ assicura che i vostri sali rimarranno pronti all′uso per mesi senza dover ricorrere ad agenti antiagglomeranti. Anche dopo numerosi utilizzi, potete stare sicuri che i vostri risultati saranno ancora accurati. Redi-Dri™ conserva le proprietà dei vostri sali più a lungo, con risparmio di tempo, energia e denaro.

Applicazioni

Il cloruro di sodio è stato utilizzato per la preparazione di: tampone salino Tris, tampone fosfato salino, tampone per lisi cellulare MPM-2 (proteina mitotica monoclonale 2), tampone di lavaggio per immunoprecipitazione, terreno di coltura LB (Luria-Bertani) e tampone di dialisi.

Metabolic-associated fatty liver disease (MAFLD) represents a spectrum of disease states ranging from simple steatosis to non-alcoholic steatohepatitis (NASH). Hepatic macrophages, specifically Kupffer cells (KCs), are suggested to play important roles in the pathogenesis of MAFLD through their activation, although

Domande

1–5 di 5 domande  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 risposta

    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 risposta

    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

  3. How long will material remain free-flowing after it is opened?

    1 risposta

    1. While the exact amount of time your material will remain free-flowing can vary, this largely depends on the ambient storage conditions and how many times it is opened.

      Utile?

  4. How does Redi-Dri™ help keep salts and buffers free-flowing?

    1 risposta

    1. Redi-Dri™ products are specially handled and the bottle is specially designed to ensure that the product will remain dry without adding impurities or additives to the product. Ensuring that you receive the highest quality material that is easy to handle.

      Utile?

  5. Are there any special storage conditions that must be maintained?

    1 risposta

    1. No, Redi-Dri™ products can be stored under the same conditions as the equivalent non-Redi-Dri™ products.
