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.

General description
Application
- Challenges in Pharmacokinetic Modelling of [(18)F]fluoro-PEG-folate PET/CT Imaging in Epithelial Ovarian Cancer Patients.: This study addresses the complexities of pharmacokinetic modeling in using Polyethylene glycol (PEG)-conjugated imaging agents for PET/CT in ovarian cancer, highlighting the adaptability and clinical implications of PEG in diagnostic imaging (Ruytenberg et al., 2024).
- Assessing the toxicity of one-step-synthesized PEG-coated gold nanoparticles: in vitro and in vivo studies.: Research into the biocompatibility of PEG-coated gold nanoparticles synthesized in a single step, evaluating their safety profile across both cellular and animal models, thus underscoring PEG′s role in enhancing nanomedicine safety (Garrigós et al., 2024).
- Microwave synthesized novel biomass carbon dots applied in the fluorescent detection of crystal violet.: The study explores the use of PEG in the synthesis of carbon dots for enhanced fluorescence in dye detection, offering insights into the broader applicative potential of PEG in environmental monitoring and safety (Yin et al., 2024).
- Modified zero-valent iron nanoparticles enhanced remediation of PCBs-contaminated soil.: Illustrating PEG′s utility in environmental cleanup, this study details the enhancement of soil remediation techniques through the application of PEG-modified nanoparticles, reflecting PEG′s versatility across different sectors (Zhao et al., 2024).

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
