Description générale

N,N′-Methylenebisacrylamide is commonly called as bis. It is used as a cross-linking agent in the preparation of polyacrylamide gels consisting of chains of acrylamide monomers. The concentration of N,N′-methylenebisacrylamide and acrylamide determines the pore size of the gel. The higher concentration of bis forms rigid gels with smaller pores due to more cross-linking leading to polymerization and vice versa.[1]

Application

N,N′-Methylenebisacrylamide has been used:
  • as a crosslinker in the monomer solution to prepare N,N-dimethyl acrylamide (DMAAm)-based cryogel and acrylamide (AAm)-based cryogel matrix[2]
  • as a crosslinker to prepare tough hydrogel network[3]
  • in the preparation of acrylamide-bisacrylamide stock solution for the preparation of polyacrylamide gel[4]

To be mixed with acrylamide for making polyacrylamide gels for use in protein and nucleic acid electrophoresis.

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
