Scientific Data

Western Blot Detection of Human Complement Factor H antibody by Western Blot. View Larger

Detection of Human Complement Factor H by Western Blot. Western blot shows lysates of human liver tissue. PVDF Membrane was probed with 2 µg/mL of Human Complement Factor H Monoclonal Antibody (Catalog # MAB4779) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Complement Factor H at approximately 155 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Background: Complement Factor H

Complement Factor H (CFH) is a 155 kDa glycoprotein that negatively regulates the alternative pathway complement cascade. It is secreted by Kupffer cells, hepatocytes, vascular endothelial cells, and platelets and circulates in the serum at high concentration. CFH interacts with cell surface polyanions and prevents local complement activation by sequestering complement component C3b, accelerating the decay of C3 and C5, and functioning as a cofactor for Factor I. CFH is composed of 20 SCR (short consensus repeats). Alternate splicing generates an isoform that is truncated following SCR7. Within SCR5-20 (aa 260-1231), human CFH shares 60% and 62% aa sequence identity with mouse and rat CFH, respectively.
