Aplicação

1-Chloro-2,4-dinitrobenzene was used in determination of relative amounts of individual glutathione S-transferases subunits in human tissues by reverse-phase HPLC[1]. It was used as contact sensitizer to study the antibacterial peptides hBD-2, -3 and -4 and LL-37 induced IL-18 protein release in human keratinocytes[2].

Ações bioquímicas/fisiológicas

2,4-dinitrochlorobenzene induces atopic dermatitis in BALB/c mice model[3].

Nota de preparo

The product is dissolved in ethanol when used as glutathione S-transferase substrate and then added to a buffer to form a final concentration of 1mM in phosphate buffer (8 mL of 0.2 M KH2PO4 and 28 mL of 0.1 M Na2HPO4 per 100 mL of solution, adjusted to pH 6.5) and 4% (v/v) ethanol.

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.
      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
