General description

Die Ketonkörper 3-Hydroxybuttersäure (BOH) und Acetessigsäure (AcAc) werden in der Leber hauptsächlich durch die Oxidation von Fettsäuren gebildet und sind normalerweise in niedrigen Konzentrationen im Urin und im Blut vorhanden. Erhöhte Ketonkonzentrationen im Blut können zu einer metabolischen Azidose führen, die mit Diabetes, Hypoglykämie im Kindesalter, Wachstumshormonmangel, Alkohol- oder Salicylatvergiftung sowie angeborene Stoffwechselstörungen assoziiert ist.

Application

Der Ketonkörper-Assay wird verwendet, um die Freisetzung von Ketonkörpern in einem Kulturmedium mit der humanen Leberkrebszelllinie HepG2 zu messen.
Geeignet für den Nachweis von Ketonkörpern (Acetessigsäure und 3-Hydroxybuttersäure) in Serum, Plasma, Urin und anderen biologischen Proben.

Biochem/physiol Actions

Bei diesem Kit werden die AcAc- und BOH-Konzentrationen mithilfe eines Enzym-Assays auf Basis von 3-Hydroxybutyratdehydrogenase-katalysierten Reaktionen bestimmt. Eine Veränderung der NADH-Extinktion, die mit einem Wert von 340 nm gemessen wurde, steht in einem direkten Verhältnis zu den AcAc- und BOH-Konzentrationen.

Features and Benefits

Kompatibel mit Handhabungssystemen mit hohem Durchsatz.

Questions

1–7 of 7 Questions  
  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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

  5. What is the sensitivity range of this kit?

    1 answer
    1. The kit is sensitive and accurate, utilizing a 10 μL sample. It offers a linear detection range of 0.12 to 8 mM for each ketone body in a 96-well plate assay.

      Helpful?

  6. Is whole blood or plasma collected in EDTA suitable for use with MAK134 Ketone Body Assay?

    1 answer
    1. Certainly, whole blood or plasma collected in EDTA is appropriate for use with this kit. During the development of the kit, these sample types were tested as they are commonly used by researchers. And also AcAc (Acetoacetic acid) is quite unstable, so it is advised using fresh samples or ones that have been frozen within the month.
