Detection of Human Complement Factor H-related 4/CFHR4 antibody by Western Blot.

Detection of Human Complement Factor H-related 4/CFHR4 by Western Blot.

Western blot shows lysates of human liver tissue. PVDF Membrane was probed with 2 µg/mL of Human Complement Factor H-related 4/CFHR4 Monoclonal Antibody (Catalog # MAB5980) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Complement Factor H-related 4/ CFHR4 at approximately 45 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Complement Factor H-related 4/CFHR4 antibody in Human PBMCs by Immunocytochemistry (ICC).

Complement Factor H-related 4/CFHR4 in Human PBMCs.

Complement Factor H-related 4/CFHR4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMC) using Human Complement Factor H-related 4 Monoclonal Antibody (Catalog # MAB5980) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: Complement Factor H-related 4/CFHR4

FHR4 (Complement factor H-related protein 4; also FHR4B and CFHR4) is a 45 kDa glycoprotein member of the factor H-related protein family. It is synthesized by hepatocytes and circulates in plasma. FHR4(B) binds to C3b and C3d. It also binds to native (pentameric) C-reactive protein (pCRP), and is suggested to promote pCRP binding to necrotic cells surfaces, thus promoting cell clearance. Mature human CFHR is 312 amino acids (aa) in length. It contains five Sushi/SCR domains, the first of which (aa 23-85) is associated with pCRP binding. There is a circulating, 86 kDa alternative splice form termed FHR4A that shows an insertion of 247 aa after Asp92. This is considered the dominant isoform, and appears to show the same activity as CFHR. Over aa 41-331, human CFHR shares 61% aa identity with a related molecule found in rat.
