詳細

Silk is a natural polymer composed of two proteins - fibroin and sericin.
Silk fibroin is used in biomedical applications due to its enhanced biocompatibility and biodegradability.

Silk fibroin (SF) demonstrates enhanced strength and stability compared to other common natural polymers due to its unique features including;
  • amphiphilicity
  • hydrophobicity
  • substantial hydrogen bonding
  • intrinsic low viscosity
  • high protein crystallinity by ß-sheet crystals.

アプリケーション

SF is a versatile material, that finds itself in multiple types of scaffolds, with extensive uses in inkjet, extrusion-based, laser-assisted, and DLP bioprinting tissue engineering applications.

Electrospinning is a versatile technique that enables the development of nanofiber-based biomaterial scaffolds. Scaffolds can be generated that are useful for tissue engineering and regenerative medicine since they mimic the nanoscale properties of certain fibrous components of the native extracellular

Although three-dimensional (3D) bioprinting technology has gained much attention in the field of tissue engineering, there are still several significant engineering challenges to overcome, including lack of bioink with biocompatibility and printability. Here, we show a bioink created from silk

質問

1–2/2 質問  

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

    1 回答

    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.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 回答

    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
