Application Abreviews Notes
IHC-P 1/250 - 1/500. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Detects a band of approximately 22 kDa (predicted molecular weight: 21 kDa).
Flow Cyt 1/440.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


ICC/IF 1/100.
IP 1/50.


  • Function

    Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed to be not involved in catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.
  • Sequence similarities

    Belongs to the complex I LYR family.
  • Cellular localization

    Mitochondrion inner membrane.
