Scientific Data

Intracellular Staining by Flow Cytometry View Larger

Detection of Isocitrate Dehydrogenase 2/IDH2 in Jurkat cells by Flow Cytometry Jurkat cells were stained with Mouse Anti-Human Isocitrate Dehydrogenase 2/IDH2 Monoclonal Antibody (Catalog # MAB11462, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Detection of Isocitrate Dehydrogenase 2/IDH2 in MCF-7 cells (Positive) and SK-MEL-28 cells (Positive). Isocitrate Dehydrogenase 2/IDH2 was detected in fixed MCF‑7 human breast cancer cell line (Positive) and SK‑Mel‑28 human malignant melanoma cell line (Positive) using Mouse Anti-Human Isocitrate Dehydrogenase 2/IDH2 Monoclonal Antibody (Catalog # MAB11462) at 8 µg/ml for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to the cytoplasm and membrane. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Detection of Isocitrate Dehydrogenase 2/IDH2 in Human Kidney. Isocitrate Dehydrogenase 2/IDH2 was detected in immersion fixed paraffin-embedded sections of human kidney using Mouse Anti-Human Isocitrate Dehydrogenase 2/IDH2 Monoclonal Antibody (Catalog # MAB11462) at 5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm and kidney tubules.

Background: Isocitrate Dehydrogenase 2/IDH2

Isocitrate dehydrogenases catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. These enzymes belong to two distinct subclasses, one of which utilizes NAD(+) as the electron acceptor and the other NADP(+). Five isocitrate dehydrogenases have been reported: three NAD(+)-dependent isocitrate dehydrogenases, which localize to the mitochondrial matrix, and two NADP(+)-dependent isocitrate dehydrogenases, one of which is mitochondrial and the other predominantly cytosolic. Each NADP(+)-dependent isozyme is a homodimer. The protein encoded by this gene is the NADP(+)-dependent isocitrate dehydrogenase found in the mitochondria. It plays a role in intermediary metabolism and energy production. This protein may tightly associate or interact with the pyruvate dehydrogenase complex.
