Product Overview
This rabbit polyclonal antibody targets NADH dehydrogenase (gene NDUFS4) in human, mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA.
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.

Immunogen
Recombinant human NDUFS4 fragment (Arg29–Lys175), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 91.8% and 90.5%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places NADH dehydrogenase in the mitochondrion inner membrane.
