Description

General description

Polyethylene glycol (PEG) is a hydrophilic polymer. It can be easily synthesized by the anionic ring opening polymerization of ethylene oxide, into a range molecular weights and variety of end groups. When crosslinked into networks PEG can have high water content, forming "hydrogels". Hydrogel formation can be initiated by either crosslinking PEG by ionizing radiation or by covalent crosslinking of PEG macromers with reactive chain ends. PEG is a suitable material for biological applications because it does not trigger an immune response.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

It has been used to modify therapeutic proteins and peptides to increase their solubility.
Photopolymerized PEG hydrogels have emerging applications in the fabrication of bioactive and immunoisolating barriers for encapsulation of cells.[1]

How can I determine the shelf life / expiration / retest date of this product?

  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
1. Technical Support

  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
