Descripción general

Brassinolide is a plant growth hormone and the most biologically active brassinosteroid (BR). It has been implicated in Auxin signaling. It has also been used for studying plant biosynthetic pathways.[1][2] Brassinolide might also regulate water-transport properties of cell membranes in Arabidopsis thaliana.[3]

Aplicación

Brassinolide has been used as a plant growth hormone.[1]

Questions

1–3 of 3 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.

  3. Please, can I know the solubility of brassinolide (B1439)? Thanks in advance. Best regards

    1 answer

    1. This product is not tested for solubility. However, a brief search of the literature reveals that this compound is soluble in the following:
      Chloroform at 10 mg/mL
      DMSO at 50 mg/mL with gentle warming
      Ethanol at 50 mg/mL with gentle warming
      Insoluble in water

      Note that this information has not been verified.
