General description

Certan Vial
Ochratoxin is a mycotoxin, produced by genus Aspergillus and Penicillium. Ochratoxin producers are widely distributed in foods such as cereals.[1] Ochratoxins are isocoumarin derivatives.[2] A quantitative detection method for ochratoxin A by using aptamer (single-stranded oligonucleotides selected in vitro to bind to molecular targets) is reported.[3]

Application

Ochratoxin A (OTA) was used in quantification of OTA in table wine by immunoaffinity column clean-up and high-performance liquid chromatography.[1] It was used as analytical standard in sample clean-up method based on immuno-ultrafiltration for the analysis of OTA in cereals.[2] It was used as analytical standard to study the influence of OTA on the rat embryonic neural cells cultured in high density “micromass cultures”.[4]

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.
      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

  3. Please I would like to know if the information contained in the certificate "The minimum recommended amount of subsample for all application types is 1 mL" is correct. Normally, it is allowed to withdraw vol. of up to 10 microliters from the standard

    1 answer

    1. The minimum recommended sub-sample is 1mL. The ampoule should be used once and not stored and re-sampled. Accuracy is optimized by transferring the maximum amount of standard solution.
