Descrizione generale

IR-783 is a near-infrared (NIR) dye with an extinction coefficient of 157000 M−1cm−1 and quantum yield of 0.11. Its excitation wavelength is in the range of 768-784 nm in saline.[1]

Applicazioni

IR-783 can be used as a starting material in the synthesis of IR-808 dye for biological applications.[2] It can also be used in the formation of NIR fluorescent human serum albumin nanoparticles for the detection of a tumor.[3] It finds potential usage as a contrasting agent for the multimodal in vivo imaging.[4]

Questions

1–4 of 4 Questions  
  1. How should it be stored?

    1 answer
    1. This product may be stored in room temperature. This product should be stored tightly closed in a dry place.

      Helpful?

  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. 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
