Product Overview
Clone 20N37 is a rabbit monoclonal antibody that recognizes NADH dehydrogenase (gene NDUFS4) in human, mouse and rat samples and is validated for Western blot, IHC, immunoprecipitation and flow cytometry. The predicted molecular weight is 20.1 kDa, and the supplier reports an observed band at about 18 kDa.
NDUFS4 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; loss of NDUFS4 in mice is a widely used model of complex I deficiency.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places NADH dehydrogenase in the mitochondrion inner membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
