Description générale

Brij® L23, also known as Polyoxyethylene (23) lauryl ether, is an ethoxylated fatty alcohol derived from lauryl alcohol. It serves as a valuable non-ionic detergent widely utilized in biochemical studies. This versatile compound is particularly well-suited for protein solubilization and membrane protein isolation, making it a key component in various biochemical assays. Brij® L23′s non-ionic nature and unique properties also position it as an essential detergent for protein extraction and cell permeabilization, facilitating a broad spectrum of research in the same. Further, its use is instrumental in preserving the structural integrity and functionality of proteins, contributing significantly to studies involving proteins and their interactions in the area of biochemical research.

Application

Brij® L23 solution has been used:
  • as a supplement of De Man, Rogosa, Sharpe (MRS) broth for monitoring bacteriocin production by lactic acid bacteria(66)
  • as a component of developing buffer for the incubation of zymogram gel for metalloproteinase quantification(67)
  • as a component of activation buffer for recombinant human hepsin(68)

Actions biochimiques/physiologiques

Brij® L23 solution is a surfactant and is used in the nanoparticle preparation by microemulsion method.[1]

Caractéristiques et avantages

High-purity product ideal for biochemical research applications

Conditionnement

Some bottles may appear indented due to the packaging process. This does not affect product integrity or quality.

Notes préparatoires

In the event that material is in the gel phase at room temperature, the customer should heat the material to a temperature range of greater than 35°C and less than 60°C, and stir the solution for approximately 15 minutes before use.

Enzymatic Assay of Cathepsin B

Cathepsin B is a lysosomal cysteine proteinase with broad specificity. This protocol uses Nα–CBZ–Arg–Arg–7–amido–4–methylcoumarin as the substrate for fluorometric detection of Cathepsin B activity.

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/418/501/product-dating-information-06-25-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
