  • Application notesIs unsuitable for WB.
  • Target

    • RelevanceActivation of the complement system plays a key role in normal inflammatory response to injury but may cause substantial injury when activated inappropriately. The complement system is activated either through the classical (antibody induced) or the alternative (microbial surface, polysacharride induced) pathway, both leading to the formation of the C5b9 complex. Fluid phase binding of the multifunctional glycoprotein S protein (vitronectin) to C5b9 leads to the formation of a cytolytically inactive complex, SC5b9, which is unable to attach to cells.

    • ab66768 staining C5b-9 (red) in porcine liver tissue by Immunohistochemistry (Frozen sections).

      Tissue was taken from allotransplants of wild-type or a1,3-galactosyltransferase gene-knockout (GTKO) pig liver, 2 hours after grafting or at necroscopy (nec). Tissue was fixed with paraformaldehyde and blocked with 20% donkey serum for 1 hour at room temperature, before being incubated with primary antibody (1/100 in diluent).
    • ab66768 staining C5b-9 in monkey retina cord tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with 0.5% Triton-X and blocked with 4% serum for 30 minutes at 22°C. Samples were incubated with primary antibody (1/500) for 16 hours at 4°C. An Alexa Fluor® 488-conjugated goat anti-mouse IgG polyclonal (1/300) was used as the secondary antibody. Counterstained with DAPI. Magnification: 20X.
