  • 関連性Complex I, or NADH ubiquinone oxidoreductase, is a large protein complex of 950,000 Da molecular weight made up by 45 to 46 different subunits. A total of seven of the subunits of the complex are encoded by mitochondrial DNA, while the remainder subunits are nuclear encoded, which are translated in the cytosol and translocated into the organelle for assembly at the inner membrane. The enzyme complex catalyses electron entry from NADH via a flavin (FMN) and several non-heme iron centers. Complex I is sensitive to a wide range of inhibitors, many of which are pesticides or other common environmental toxins, such as rotenone. Complex I dysfunction is a common cause of genetic OXPHOS defects. Altered functioning of this complex is also thought to contribute to several neurological disorders including Parkinson’s disease and schizophrenia. Also, there is evidence of Complex I involvement in diabetes.

Anti-Complex I Immunocapture antibody [18G12BC2] 画像

  • Immunocytochemistry image of ab109798 stained fibroblasts cells. The cells were paraformaldehyde fixed (4%, 20 minutes) and Triton X-100 permeabilized (0.1%, 15 minutes). The cells were incubated with the antibody (ab109798, 1 µg/mL) for 2 hours at room temperature or over night at 4°C. The secondary antibody was (green) Alexa Fluor® 4884 goat anti-mouse IgG (H+L) at a 1/1000 dilution for 1 hour. 10% Goat serum was used as the blocking agent for all blocking steps. The target protein locates to the mitochondria.
  • HL-60 cells were stained with 1 µg/mL Complex I antibody ab109798 (blue) or an equal amount of an isotype control antibody (red) and analyzed by flow cytometry.
  • Overlay histogram showing HepG2 cells stained with ab86750 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab867508, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed.

This antibody is an immunocapture antibody which can pull down the whole complex I from a given sample. It works also as a ICC and Flow antibody. It's a weak WB antibody, light up a 8kda subunit of complex I but we have difficulty to identify which sub...

whole (45 subunit, 900 kDa) active bovine Complex I - this was shown with mass spec.

It is excellent at binding native, active complex I but has proven difficult to identify the exact subunit to which it binds.

Thank you for contacting Abcam.

I have attached a paper that looks at the structure of complex 1 and Table 1 has a complete list of the subunits and I believe (but I am no expert in this field) that S1 is also known as NDUFS1.
