General description

Rhodamine 6G (R6G) is an organic laser dye and can be used to study the probes as it has a high quantum yield for fluorescence. It can be used as a fluorescence tracker which helps in defining the spectroscopic characteristics for achieving a high conversion efficiency and precision of measurements. The absorption of R6G in different solvents can range between 400-700 nm.[1][2]

Application

R6G can be used as a cationic dye to determine the photocatalytic ability of TiO2 reinforced graphene oxide composites that can be potentially used in self-cleaning applications.[3][4] It can be used to calculate the quantum yield of glutathione-capped copper nanoclusters (CuNCs) for fluorescent thermo-responsive nanomaterials[5] and gold nanoparticles (AuNPs) for fluorescent/X-ray computed tomography.[6]

Biochem/physiol Actions

A rhodamine analog useful in Pgp efflux assays. Has been used to characterize kinetics of MRP1- mediated efflux.

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
