應用

Poly(2-(dimethylamino)ethyl methacrylate) is a pH-responsive polymer. pH-responsive polymers are a group of stimuli-responsive polymers that can respond to solution pH by undergoing structural and property changes such as surface activity, chain conformation, solubility, and configuration. The term “pH-responsive polymers” is commonly used to describe polymers having ionisable acidic or basic residues whose ionization depends on solution pH. The physical properties of the polymer, such as its chain conformation, configuration, and solubility, can be tailored by manipulating the pH or ionic strength. These unique properties of pH responsive polymer systems consequently make them very useful in various applications such as drug delivery, gene delivery, sensors, surfaces, membranes, and chromatography.
pH-sensitive polymer systems combined with nanotechnology could be utilized as an alternative strategy to traditional targeting systems to overcome major problems in current chemotherapy represented by non-specific tissue distribution of the drugs, tumor heterogeneity, and multidrug resistance (MDR) against anticancer drugs.

Questions

1–2 of 2 Questions  

  1. 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

  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
