Beta-Hydroxybutyrate Fluorometric Assay Kit

Beta-Hydroxybutyrate (Beta-HB) is the most abundant of the ketone bodies (~78% of total ketone bodies in blood). Ketoacidosis (high concentrations of the ketone bodies) can be caused by a variety of conditions, such as diabetes, alcoholism and severe starvation. Ketoacidosis can be fatal if not treated. Additionally, ketogenic diets can increase the concentration of ketone bodies slightly in healthy individuals. Assay Genie's Beta-Hydroxybutyrate Assay Kit offers simplicity, enhanced sensitivity, and can be adapted to high-throughput applications. The assay is based on enzymatic oxidation of Beta-HB that results in generation of fluorescent signal (Ex/Em = 535/587 nm) which is directly proportional to the amount of Beta-HB. The kit offers an excellent alternative for measurement of Beta-HB when biological sample quantities are limited or subketogenic levels are suspected. The assay can detect Beta-Hydroxybutyrate as low as 4 µM in a variety of biological samples.

All samples were deproteinized using 10 kDa Spin Column spiked with known amount of β-Hydroxybutyrate (400 pmol). Assays were performed following the kit protocol.
