Product Overview
This rabbit polyclonal antibody targets isocitrate dehydrogenase (gene IDH2) in human, mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 50.9 kDa, and the supplier reports an observed band at about 45 kDa.
IDH2 is the mitochondrial NADP+-dependent isocitrate dehydrogenase that converts isocitrate into α-ketoglutarate and generates NADPH in the mitochondrial matrix. It contributes to redox balance and intermediary metabolism, and recurrent IDH2 mutations that produce 2-hydroxyglutarate are found in acute myeloid leukemia and gliomas.

Samples with a confirmed band (WB): human Jurkat cells, human THP-1 cells, human MCF-7 cells, human HEL cells, rat heart tissue, rat liver tissue, mouse heart tissue, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon cancer tissue, human ovarican cancer tissue, mouse heart tissue, rat heart tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): A549 cells.
Immunogen
Synthetic peptide from the C-terminal region of human IDH2. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places isocitrate dehydrogenase in the mitochondrion. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
