Product Overview
This rabbit polyclonal antibody targets NADH dehydrogenase (gene NDUFS5) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 12.5 kDa, and the supplier reports an observed band at about 15 kDa.
NDUFS5 is an accessory subunit of mitochondrial complex I (NADH:ubiquinone oxidoreductase), the large enzyme of the inner mitochondrial membrane that passes electrons from NADH to ubiquinone and starts the respiratory chain. Accessory subunits are not thought to take part in catalysis but help build and stabilize the complex, and they are used as markers in studies of mitochondrial function and oxidative phosphorylation.

Immunogen
Recombinant human NDUFS5 fragment (Met1–Pro106), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places NADH dehydrogenase in the mitochondrion inner membrane and mitochondrion intermembrane space. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
