Application

Il saccarosio può essere usato per preparare gradienti di densità per la separazione di cellule o organuli.[1][2] L′indice di rifrazione della soluzione sarà in correlazione diretta con la densità.[2] Inoltre, il saccarosio può essere usato come supplemento in terreni di coltura per vegetali, insetti e batteri, oltre che in diversi saggi enzimatici.

Other Notes

Per acquisire un quadro completo della nostra ampia selezione di disaccaridi disponibili per la vostra ricerca, vi invitiamo a consultare la nostra pagina dedicata ai carboidrati.

Preparation Note

È possibile sterilizzare le soluzioni in autoclave per 15-20 minuti a una temperatura massima di 121 °C. Avrà luogo una quota di idrolisi a glucosio e fruttosio, che in parte dipenderà dalla rapidità con cui l′autoclave raggiunge temperatura e pressione richieste. È necessario fare attenzione a evitare che le soluzioni si caramellizzino.

Domande

1–4 di 4 domande  
  1. 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/418/501/product-dating-information-06-25-mk.pdf

  3. What does BIOXTRA mean?

    1 risposta
    1. BIOXTRA grade products undergo stringent testing protocols, which may include trace metal analysis and specialized suitability testing, such as hybridoma or mouse embryo testing. These products also include application-specific formulations, such as tablets and prepared solutions.

      Utile?

  4. 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
