General description

Isocitrate (Isocitric Acid) is a substrate in the citric acid (TCA) cycle. Isocitrate is formed by the isomerization of citrate catalyzed by the enzyme aconitase. Isocitrate is oxidized by isocitrate dehydrogenase producing α-ketoglutarate and generating NADPH. Isocitrate is commonly found in many fruits and vegetables and their processed products. Industrially, isocitrate is used as a marker to identify the quality and purity of fruit juices.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for the quantitative determination of isocitrate and evaluation of drug effects on its metabolism in food, beverage and biological samples (e.g. cell lysate, tissue homogenate, serum, etc.).

Principle

This Isocitrate Assay Kit measures the NADPH generated from the oxidation of isocitrate. The NADPH reduces a probe into a highly fluorescent product. The fluorescence intensity of this product, measured at ex = 530 nm/ em = 585 nm, is proportional to the isocitrate concentration in the sample.

Metabolic reprogramming is a central hallmark of cancer. Therefore, targeting metabolism may provide an effective strategy for identifying promising drug targets for cancer treatment. In prostate cancer, cells undergo metabolic transformation from zinc-accumulating, citrate-producing cells to citrate-oxidizing malignant cells with
