• Tag: C-Myc/DDK
• Predicted MW: 46.5 kDa
• Concentration: >50 ug/mL as determined by microplate BCA method
• Purity: > 80% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: 25 mM Tris.HCl, pH 7.3, 100 mM glycine, 10% glycerol
• Bioactivity: Enzymatic activities were determined by monitoring NADPH formation based on the absorbance at 345nm. The reaction was carried out at 37? for 10 minutes in the presence of isocitrate as a substrate and NADP as a cofactor. The data which presented a good linear relation on the curve was used to calculate the specific activity, and one unit is defined as converting 1.0 umole of NADP to NADPH per min at 37?. In summary, the wildtype IDH1 produced from HEK293 cells and insect cells are active while the R132H mutant or the WT/R132H heterodimers are inactive.
• Preparation: Recombinant protein was captured through anti-DDK affinity column followed by conventional chromatography steps.
• Note: For culture applications, please filter before use. Note that you may experience some loss of protein during the filtration process.
• Storage: Store at -80°C.
• Stability: Stable for 12 months from the date of receipt of the product under proper storage and handling conditions. Avoid repeated freeze-thaw cycles.

• Summary: 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 cytoplasm and peroxisomes. It contains the PTS-1 peroxisomal targeting signal sequence. The presence of this enzyme in peroxisomes suggests roles in the regeneration of NADPH for intraperoxisomal reductions, such as the conversion of 2, 4-dienoyl-CoAs to 3-enoyl-CoAs, as well as in peroxisomal reactions that consume 2-oxoglutarate, namely the alpha-hydroxylation of phytanic acid. The cytoplasmic enzyme serves a significant role in cytoplasmic NADPH production. Alternatively spliced transcript variants encoding the same protein have been found for this gene.
