Product Overview
This rabbit polyclonal antibody detects isocitrate dehydrogenase (gene IDH3A) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 39.6 kDa, and the supplier reports an observed band at about 37 kDa.
IDH3A is the catalytic α subunit of NAD+-dependent isocitrate dehydrogenase (IDH3), the tricarboxylic acid cycle enzyme that turns isocitrate into α-ketoglutarate in mitochondria. It pairs with the β and γ subunits to form the fully active heterotetramer, which is a key control point of the cycle.
