General description

Poly (ethylene glycol) (PEG) is non-ionic, hydrophilic and non-toxic polymer. It is widely used in the emerging field of polymer‐based drug delivery.[1] PEG is available in different molecular weights. It facilitates the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. It also interacts with cell membrane, thereby allowing cell fusion.[2]

Application

Poly(ethylene glycol) has been used in the preparation of methyl cellulose (MC)-based polymer electrolytes.[3] It has also been used as a solvent to analyse the molecular weight cut off and rejection studies of nanofiltration membranes.[4]

Questions

1–3 of 3 Questions  

  1. 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
