Detection of Human Complement Component C9 by Western Blot. Western blot shows lysates of human plasma. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human Complement Component C9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8126) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Complement Component C9 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Complement Component C9
Complement Component 9 (C9) is a 65-70 kDa protein of the complement membrane attack complex (C5b-9) that binds C5b-8, polymerizes, and forms pores upon activation of the complement cascade. Mature human C9 shares 60% and 66% amino acid sequence identity with mouse and rat C9, respectively. It may be proteolytically cleaved by thrombin into a 28-34 kDa cysteine-rich, mannosylated soluble C9a subunit, and a 37-38 kDa membrane-anchored N-glycosylated C9b. These fragments are also able to polymerize.
