一般描述

聚乙二醇（PEG）是乙二醇聚合物，具有亲水性。PEG具有高水合能力并且结构灵活。由于PEG具有生物相容性并且结构中不存在空间位阻，因此，它在用作药物结合物方面具有优势。[1]

应用

聚乙二醇已被用于：
  • 酵母的转化缓冲液[2]
  • 作为登革病毒分离缓冲液的成分[3]
  • 慢病毒颗粒的浓缩[4]
  • 疱疹病毒核出口复合物（NEC）的结晶化[5]

生化/生理作用

美国食品和药品监督管理局（FDA）批准PEG用作药物结合物，它是非免疫原性且安全的。[6]PEG被广泛用作生物化学和分子生物学实验的试剂。[7]PEG结合改善了糖尿病药物格列齐特的溶解度和溶出度。[8]它被用于碳纳米管官能化。[9]在富含单宁的树叶中，PEG 8000的存在可提高代谢能（ME）含量和气体产生。[10]

Polyethylene Glycol (PEG) Selection Guide

Polyethylene glycol (PEG), also sometimes referred to as polyethylene oxide (PEO), is a condensation polymer of ethylene oxide and water that has several chemical properties that make it useful for biological, chemical and pharmaceutical applications.

Questions

1–3 of 3 Questions  

  1. Is this product heat and light sensitive?

    1 answer

    1. This material is not reportedly light or heat sensitive.

      Helpful?

  2. 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

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

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
