Application

Brij® L23 is a detergent used for measuring the concentration of carbon black in lung tissues.[1] It has also been used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase.[2] Additionally, the product has also been used for assessing whether acrolein could lead to pro-enzyme activation by using gelatin zymography.[3]

Biochem/physiol Actions

Brij® L23 also referred to as Brij 35 or Polyoxyethylene (23) lauryl ether is a non-ionic detergent that lowers the non-specific protein adsorption and reduces electroosmotic pumping drastically.[4] This allows the pH to be varied without adversely affecting the flow rate. It also used as a nonionic surfactant that decreases the absorbance of the blank, inhibits turbidity as well as provides linearity.[5]

Other Notes

Non-ionic polyoxyethylene ether.[6] Used for selective and rapid solubilization of microbial membrane aldehyde dehydrogenase.[2]

Questions

1–3 of 3 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
