Overview

  • Product name
  • Description
    Rabbit polyclonal to C9
  • Specificity
    This product may also detect C9 within the C5b-9 complex, but we have no evidence to show this. Any feedback from our customers is welcome. We recommend ab55811 for specifically detecting the C5b-9 complex.

Our Abpromise guarantee covers the use of ab64011 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 63 kDa).

Target

  • Function
    Constituent of the membrane attack complex (MAC) that plays a key role in the innate and adaptive immune response by forming pores in the plasma membrane of target cells. C9 is the pore-forming subunit of the MAC.
  • Tissue specificity
    Plasma.
  • Involvement in disease
    Defects in C9 are a cause of complement component 9 deficiency (C9D) [MIM:613825]. A rare defect of the complement classical pathway associated with susceptibility to severe recurrent infections, predominantly by Neisseria gonorrhoeae or Neisseria meningitidis.
  • Sequence similarities
    Belongs to the complement C6/C7/C8/C9 family.
    Contains 1 EGF-like domain.
    Contains 1 LDL-receptor class A domain.
    Contains 1 MACPF domain.
    Contains 1 TSP type-1 domain.
  • Post-translational
    modifications
    Thrombin cleaves factor C9 to produce C9a and C9b.
    Phosphorylation sites are present in the extracelllular medium.
  • Cellular localization
    Secreted. Cell membrane. Secreted as soluble monomer. Oligomerizes at target membranes, forming a pre-pore. A conformation change then leads to the formation of a 100 Angstrom diameter pore.

Thank you for your inquiry.

I can confirm that both antibodies may also detect C9 within the C5b-9 complex, but we have no evidence to show this. Any feedback from our customers is welcome.

Both antibodieswere raised against an immu...

Thank you for your enquiry. The reason that the molecular weight is different could be that the C5-b-9 complex degrades under proteolysis and therefore on a western blot, we are only seeing degradation products. In this case, it is the phosphoryla...
