DESCRIPTION

General description

The aconitases are a family of iron-sulfur containing enzymes that catalyzes the isomerization of citrate to isocitrate. Two aconitases, encoded by different genes, have been identified in eukaryotes. Aconitase 1 (ACO1, c-aconitase) is a cytosolic enzyme while Aconitase 2 (ACO2, m-aconitase) is a mitochondrial enzyme that functions in the tricarboxylic acid cycle. Aconitases are reversibly inactivated by oxidative stress, and aconitase activity in cells and tissues has been used as a biomarker for oxidative damage.

Application

Aconitase Activity Assay Kit has been used to measure the activity of cytosolic and mitochondrial aconitase enzyme.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for the measurement of aconitase activity in biological samples including tissue and cells

Principle

The Aconitase Activity Assay kit provides a simple and direct procedure for measuring Aconitase activity in a variety of samples. Aconitase activity is determined in a coupled enzyme reaction in which citrate is converted to isocitrate by aconitase. This results in a colorimetric (450 nm) product proportional to the enzymatic activity present. One unit of aconitase is the amount of enzyme that will isomerize 1.0 μmole of citrate from isocitrate per minute at pH 7.4 at 25 °C.
