일반 설명

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.

적합성

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

원리

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).

Isocitrate dehydrogenase (IDH) is a reversible enzyme that catalyzes the NADP(+)-dependent oxidative decarboxylation of isocitrate (ICT) to α-ketoglutarate (αKG) and the NADPH/CO(2)-dependent reductive carboxylation of αKG to ICT. Reductive carboxylation by IDH1 was potently inhibited by NADP(+) and, to a

1–3 / 3 질문  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 답변

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. What is the recommended approach for measuring 2-HG levels in cell culture samples using the MAK320 detection kit if the sample volume is very small (i.e. 100 ul) and there is no access to equipment for accurately measuring pH in small volumes? Additionally, is the pH range critical for the experiment to work? Would a higher or lower pH result in decreased enzyme activity or render the experiment ineffective?

    1 답변

    1. The recommended solution is to use litmus paper to measure the pH of the sample. Another option is to use a special electrode designed for very small volumes, although this can be complicated and expensive. While the pH of the sample is crucial for test performance, the pH range is wide, making pH paper suitable and requiring only a few microliters of the sample.
