Description générale

Microcystin-LR belongs to the group of cyclic heptapeptide metabolites called microcystins, produced by cyanobacterium (blue-green algae) Microcystis aeruginosa, and others.

Application

The analytical standard can also be used as follows:

  • Development of a paper immunosensor based on nanobiochar particles (nBC) and anti-microcystin-LR monoclonal antibodies (mAbs) for the identification of microcystin-LR in environmental water samples
  • Determination of microcystin-LR in tap water samples using a lateral flow immunochromatographic assay (LFICA) procedure based on molecularly imprinted polymers and enzyme-assisted color change approach
  • Fluorescence-based detection of microcystin-LR in tap water and serum samples by an aptasensor, constructed using single-walled carbon nanotubes (SWNTs) and dapoxyl fluorescent dye
  • Analysis of surface water samples for the detection of microcystin-LR using ultra high-performance liquid chromatography-mass spectrometry (UHPLC-MS) and high-performance liquid chromatography-variable wavelength-Ultraviolet Detector (HPLC-VW-UVD) methods
  • Determination of microcystin-LR in surface water samples using high-performance liquid chromatography coupled to tandem mass spectrometry with electrospray ionization source (HPLC-ESI-MS/MS).[1]

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
