IDK® Bile Acids Photometric Kit (Stool)

The IDK® Bile Acids Photometric Kit (Stool) is intended for the quantitative determination of bile acids in stool.

For research use only. Not for use in diagnostic procedures.

For Laboratory Professional Use Only.

This kit is compatible with our IDK Extract® Stool Sample Preparation System.

This is the RUO version of Immundiagnostik part number K 7878W.

Test Principle of the IDK® Bile Acids Photometric Kit

In the presence of excess thio-NAD, bile acids are converted to 3-keto steroids by the enzyme 3-a-hydroxysteroid dehydrogenase while thio-NADH is formed. The formation rate of thio-NADH can be determined by the change of absorbance (DOD) at 405 nm.

A dose-response curve DOD vs. concentration is generated using the values obtained from measured standards. The bile acids concentration of the samples is determined directly from this curve.
