Allgemeine Beschreibung

Poly(ethylenoxid)(PEO) ist ein nichtionisches wasserlösliches Polymer mit hoher Molekülmasse. Es bildet einGel bei der Hydrierung und weist eine gute Quellkapazität auf. PEO-Polymere sind nichttoxischund werden verbreitet in Arzneimittelabgabesystemen verwendet, um die Arzneimittellöslichkeit zu verbessern.

Anwendung

Poly(ethylenoxid) kann zum Herstellen von Folgendem verwendet werden:
  • Bioabsorbierbare und injizierbare Hydrogele für die verzögerte Arzneimittelfreisetzung.
  • PEO/Graphenoxid-Verbundmaterial-Elektrolytmembran für Brennstoffzellen.
  • Poly(ethylenoxid)-b-poly(ε-caprolacton)(PEO-b-PCL)-Diblockcopolymer. Losartankalium-eingekapseltes (PEO-b-PCL) Copolymer kann als Arzneimittelträger verwendet werden.

Polymeric hydrogels long have attracted interest for biomaterials applications because of their generally favorable biocompatibility. High in water content, they are particularly attractive for delivery of delicate bioactive agents, such as proteins. However, because they require covalent crosslinking for gelation

We report on the preparation of drug nanocarriers by encapsulating losartan potassium (LSR) into amphiphilic block copolymer micelles, utilizing the biocompatible/biodegradable poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) diblock copolymer. The PEO-b-PCL micelles and LSR-loaded PEO-b-PCL nanocarriers were prepared by organic solvent evaporation method

Previous studies have demonstrated that Separan AP-30, a drag-reducing polymer, significantly decreased the formation of atherosclerotic plaques in rabbits fed a high-cholesterol diet. Furthermore, Separan AP-273, a polymer similar to but longer than Separan AP-30, markedly increased cardiac output in

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.

Questions

1–2 of 2 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.

  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
