    Abcam's beta Hydroxybutyrate (beta HB) Assay Kit (Colorimetric) (ab83390) utilizes beta HB Dehydrogenase to generate a product which reacts with our colorimetric probe with an absorbance band at 450 nm. The kit is an easy and accurate assay to measure beta HB levels in biological samples. The assay is linear for 1-20 nmol beta HB in up to 100 µL samples or 0.01-0.2 mM of beta HB samples.

  • 特記事項

    Diabetic ketoacidosis occurs when circulating insulin levels drop to very low levels, shutting off the supply of glucose to the body. The physiological response is for the liver to produce ketone bodies (acetoacetate, acetone, and primarily beta-hydroxybutyrate) from the acetyl CoA produced from fatty acid oxidation. The very high rate of ketone body production outstrips the body's ability to utilize them as an energy source and the blood concentration builds up. As rather strong acids, they result in a significant drop in blood pH.

  • Beta hydroxybutyrate in mouse tissue lysates showing quantity (nmol) per mg protein of tested sample

  • Beta hydroxybutyrate measured in biological fluids showing quantity (nmol) per microliter of tested sample

  • beta HB Standard Curve: Assays were performed following ab83390 kit protocol.
  • Human serum samples were filtered using a 10 kda MW cut-off spin filter (ab93349) spun at 14,000 RPM for 30 minutes. Beta Hydrobutyrate (BHB) was detected on a 96-well plate using ab83390.

    Young control group (6 men, 25±1 years old).
    Age-matched control group (13 men, 69±7 years old)
    PD = Individuals diagnosed with idiopathic PD (15 men, 71±8 years old, duration of disease = 10±6 years, H&Y = 2.3±0.7, median = 2).

    A trend approaching significance in increased levels of BHB in the plasma of PD patients compared to age-matched controls was observed. BHB is known to fluctuate in a variety of conditions including starvation, diabetes mellitus and other co-morbidities.

  • The plasma levels of total BHB was detected using ab83390. Five rats were in each group. Samples were collected from tail vein blood and were transferred into EDTA-containing tubes. After centrifugation at 1500×g for 15 min at room temperature, the plasma was transferred into a new tube and stored at -80°C until use. Values are presented as the mean ± S.E. (**p<0.01).

レビューと Q&A

The detection agent does not quantify the oxobutyrate but the byproduct of the reaction by the dehydrogenase. The reaction byproducts are produced proportionally based on the amount of beta hydroxybutyrate in a specific sample. This is why this assay k...

Thank you for your enquiry and interest in our products.

I can confirm that this kit (ab83390: beta Hydroxybutyrate (beta HB) Assay Kit) measuresonly the β-Hydroxybutyrate in the samples.

Hope this information has been helpful ...

Thank you for your inquiry.
I can confirm that frozen serum or plasma samples are suitable for this kit.
We did not experimentally test frozen versus fresh samples but would expect a slight loss of activity in frozen samples.
This will n...
