Description

Application

Diethylene glycol (diglycol) is used in biomaterials engineering to functionalize peptide nanofibers to improve their aggregation and proteolytic degradation properties. Diethylene glycol may be used as a solvent, reducing agent and derivatizing agent in the preparation of various types of nanoparticles.

Cuprous oxide nanoparticles dispersed on reduced graphene oxide as an efficient electrocatalyst for oxygen reduction reaction.

Xiao-Yan Yan et al.

Chemical communications (Cambridge, England), 48(13), 1892-1894 (2012-01-10)

Cuprous oxide (Cu(2)O) nanoparticles dispersed on reduced graphene oxide (RGO) were prepared by reducing copper acetate supported on graphite oxide using diethylene glycol as both solvent and reducing agent. The Cu(2)O/RGO composite exhibits excellent catalytic activity and remarkable tolerance to

Diethylene glycol functionalized self-assembling peptide nanofibers and their hydrophobic drug delivery potential.

Parisa Sadatmousavi et al.

Acta biomaterialia, 8(9), 3241-3250 (2012-05-30)

Self-assembling peptide nanofibers have emerged as important nanobiomaterials, with such applications as delivery of therapeutic agents and vaccines, nanofabrication and biomineralization, tissue engineering and regenerative medicine. Recently a new class of self-assembling peptides has been introduced, which takes into consideration

Glycodendrimeric phenylporphyrins as new candidates for retinoblastoma PDT: blood carriers and photodynamic activity in cells.

Ze-Jian Wang et al.

Journal of photochemistry and photobiology. B, Biology, 115, 16-24 (2012-07-17)

Photodynamic therapy (PDT) has recently been proposed as a possible indication in the conservative treatment of hereditary retinoblastoma. In order to create photosensitizers with enhanced targeting ability toward retinoblastoma cells, meso-tetraphenylporphyrins bearing one glycodendrimeric moiety have been synthesized. The binding

  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
