General description

Twelve different types of bile acids are typically found in mammals, among them two primary types are cholic acid and chenodeoxycholic acid. These can be dehydroxylated into secondary bile acids. Finally, these four can be conjugated to either taurine or glycine creating 8 different conjugated bile acids. Bile acid levels in feces, blood, urine, and bile can be used as markers for various diseases such as hyperlipidemia, cholestasis, gall stones, colon cancer, etc. Bile acids also exist as sulfate salt forms known as bile acid sulfates. Sulfation of bile acids increases their solubility and decreases intestinal absorption, thereby enhancing fecal and urinary excretion.

Application

Bile Acid Assay Kit has been used to quantify bile acid levels from plasma.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for the quantitative determination of total bile acids and evaluation of drug effects on bile acid metabolism in serum, plasma, urine and other biological samples.

Principle

This Bile Acid Assay Kit provides a convenient fluorimetric means to measure total bile acids in biological samples. In the assay, 3–hydroxysteroid dehydrogenase reacts with all twelve bile acids, converting NAD to NADH, which reduces a probe to a highly fluorescent product. The resulting fluorescence intensity (γex = 530 nm/γem = 585 nm) is linear to the bile acid concentration in the sample.

Storage Class Code

10 - Combustible liquids

The liver excretes excess cholesterol in the form of bile acids. Bile acids serve two purposes: to remove unwanted cholesterol from the body and to aid in lipid digestion in the intestine.
