Allgemeine Beschreibung

Supelite DAX-8 is a nonfunctionalised resin with strong hydrophobic organic matter endorsed to humic and fulvic acids.[1] It is also referred as polymethylmethacrylate resin.[2]

Anwendung

Adsorberharz mit mittlerer Polarität für Verbindungen bis MW = 150000. Meist genutzt für die Adsorption von Fulvin- und Huminsäuren, Behandlung von Abwasser aus der Papiergewinnung und Entfernung von Alkohol, Tensiden und Farbstoffen aus Proben.
Supelite DAX-8 was used as an absorbent in:
  • HPLC-SEC fractionation system[2]
  • column chromatography[2]
  • extraction procedure and extracts were analysed using Cary Eclipse fluorescence spectrophotometer[3]

Angaben zur Herstellung

DAX-8 is a salt imbibed resin, which requires some preparation prior to use. In the protocol below, you may use methanol in place of ethanol.
  • First, rinse the adsorbent resin with 2-3 bed volumes (BV) of distilled water.
  • Soak overnight in 2 BV of 95% ethanol.
  • After soaking, the resin is introduced into the column and rinsed with an additional 2 BV of 95% ethanol.
  • Rinse with 2 BV of distilled water to displace the ethanol, followed by 1 BV of 4% (w/v) sodium hydroxide, 2 BV of distilled water, 1 BV 4% (v/v) hydrochloric acid, and finally by distilled water until the pH of the eluent becomes neutral.

CRISPR-Cas9 proteins function within bacterial immune systems to target and destroy invasive DNA and have been harnessed as a robust technology for genome editing. Small bacteriophage-encoded anti-CRISPR proteins (Acrs) can inactivate Cas9, providing an efficient off switch for Cas9-based applications.

Fragen

1-4 von 4 Fragen  

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

    1 Antwort

    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 Antwort

    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.
