Scientific Data

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

Detection of Mouse Complement Factor H by Western Blot. Western blot shows mouse plasma and lysate of mouse liver tissue. PVDF Membrane was probed with 2 µg/mL of Rat Anti-Mouse Complement Factor H Monoclonal Antibody (Catalog # MAB4999) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). Specific bands were detected for Complement Factor H at approximately 200 and 117 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunocytochemistry/ Immunofluorescence Detection of Mouse Complement Factor H  by Immunocytochemistry/Immunofluorescence View Larger

Detection of Mouse Complement Factor H by Immunocytochemistry/Immunofluorescence Histologic evidence of AP activation in experimental MN. Glomerular deposition of properdin (A), factor H (B), and C4d (C) was evaluated by indirect immunofluorescence staining of frozen kidney sections from alpha 3NC1-immunized D1 mice and adjuvant-immunized control mice. Properdin and factor H staining along the capillary loops was found in alpha 3NC1-immunized D1 mice, but not in adjuvant-immunized mice. Mesangial C4d staining was found in all mice, while weaker segmental staining for C4d along capillary loops was also present in alpha 3NC1-immunized mice.

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 SCR15 - 20 (aa 857-1234, which encompass the primary binding sites for heparin and C3b), human CFH shares 60% and 63% aa sequence identity with mouse and rat CFH, respectively.
