Test principle : This assay employs a two-site sandwich ELISA to quantitate B-OHB in samples. An antibody specific for B-OHB has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyB-OHB present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conj µgated antibody specific for B-OHB is added to the wells. After washing, Streptavidin conj µgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of B-OHB bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview : Beta-Hydroxybutyric acid is a ketone body. It is a chiral compound having two enantiomers, D-3-hydroxybutyric acid and L-3-hydroxybutyric acid. Like the other ketone bodies, levels of beta-hydroxybutyrate are raised in ketosis. In humans, beta-hydroxybutyrate is syntheVolumed in the liver from acetyl-CoA, and can be used as an energy source by the brain when blood glucose is low. Diabetic patients can have their ketone levels tested via urine or blood to indicate diabetic ketoacidosis. In alcoholic ketoacidosis, this ketone body is produced in greatest concentration. Both types of ketoacidosis res µLt in an increase B-Hydroxybutyrate to oxaloacetate ratio, res µLting in TCA cycle stalling and shifting of glucose towards ketone body production.Industrially, it can also be used for the synthesis of biodegradable plastics, such as poly. This polymer can be produced biologically by the bacteria, Alcaligenes eutrophus.
Stability : The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calc µLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
