DESCRIPTION

General description

The level of D-2-Hydroxyglutarate (D2HG) is low in normal cells and tissues, but is significantly elevated in metabolic diseases, such as the rare autosomal disorder D2HG aciduria. D2HG is mildly elevated in other metabolic disorders including multiple acyl-CoA dehydrogenase deficiency, dihydrolipoyl dehydrogenase deficiency, pyruvate decarboxylase deficiency and pyruvate carboxylase deficiency, various cancers, and in neoplasms with mutations in the isocitrate dehydrogenase 1 (IDH1) and isocitrate dehydrogenase 2 (IDH2) genes. Detection of elevated D2HG is an important biomarker for early diagnosis, prognosis, monitoring and the development of therapeutic strategies against these diseases.

Suitability

Suitable for the detection of D2HG levels in cells and tissues lysates, serum, urine, cultured cells and culture supernatants.

Principle

Developed in partnership with the German Cancer Research Center (DKFZ), the D2HG Assay Kit is a rapid and sensitive enzymatic assay for the detection of D2HG levels in various biological fluids: serum, urine, cell culture supernatants, and cell or tissue lysates. The assay, originally developed by Balss et al., 8 is based on the oxidation of D2HG to α-ketoglutarate (αKG) by the enzyme (D)-2-hydroxyglutarate dehydrogenase (HGDH) coupled to the reduction of NAD+ to NADH (see Figure 1). The amount of NADH formed is then quantitated by the diaphorase mediated reduction of resazurin to the fluorescent dye resorufin (λex = 540 nm/λem = 590 nm).
