General description

β-Hydroxybutyrate, also known as 3-Hydroxy-butyrate, is a ketone body primarily synthesized in the liver from the oxidation of fatty acids. Ketone body formation, ketogenesis, is elevated when blood glucose levels drop. Moderately elevated blood ketone bodies occur normally during fasting and prolonged exercise. During alcoholic or diabetic ketoacidosis, blood levels of β-hydroxybutyrate can rise to abnormally high levels. β-hydroxybutyrate can be used as a marker for hepatic energy metabolism. β-hydroxybutyrate formation increases with excessive acetyl-CoA, and serves as a source of energy to the brain.[1]

Application

β-Hydroxybutyrate Assay Kit has been used
  • to quantify the level of β-hydroxybutyrate in plasma/serum[2][3][4]
  • to study the change in myocardial 18F-FDG uptake upon extended ketogenic diet, by measuring the level of plasma ketone bodies[5]
  • to study the role of β-hydroxybutyrate in the treatment of impairment and neuropathic pain in spinal cord-injured mice[6]

Suitability

Suitable for the measurement β-Hydroxybutyrate levels in biological samples including serum and urine

Principle

In this assay, β-Hydroxybutyrate concentration is determined by a coupled enzyme reaction, which results in a colorimetric (450 nm) product, proportional to the β-Hydroxybutyrate present.

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.
