Allgemeine Beschreibung
Poly(ethylenglycol) (PEG) ist ein Polymer aus Ethylenglycol-Einheiten und hat hydrophile Eigenschaften. PEG verfügt über eine ausgeprägte Hydrationsfähigkeit und ist strukturell flexibel. Aufgrund seiner Biokompatibilität und der Abwesenheit von sterischen Hindernissen in seiner Struktur ist PEG als Arzneimittelkonjugat vorteilhaft.[1]
Anwendung
Biochem./physiol. Wirkung
Die Food and Drug Administration (FDA) erteilte PEG die Zulassung als Arzneimittelkonjugat, es ist nicht-immunisierend und sicher.[6] PEG wird in biochemischen und molekularbiologischen Experimenten häufig als Reagenz genutzt.[7] Eine PEG-Konjugation verbessert die Löslichkeit und Auflösung des Antidiabetikums Gliclazid.[8] Es wird bei der Funktionalisierung von Kohlenstoffnanoröhrchen verwendet.[9] Das Vorhandensein von PEG 8000 in Tannin-freien Blättern steigert die Menge metabolisierbarer Energie (ME) und die Gasproduktion.[10]

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

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