Product Overview
This rabbit polyclonal antibody targets complement factor H (gene CFH) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 139.1 kDa, and the supplier reports an observed band at about 150 kDa.
Complement factor H (CFH) is a major plasma regulator of the alternative complement pathway. It binds C3b on host cells, speeds the decay of the C3 convertase and acts as a cofactor for factor I, protecting self tissues from complement attack; variants of CFH are well established in age-related macular degeneration and atypical hemolytic uremic syndrome.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human hccp tissue, rat liver tissue, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with a confirmed signal (flow cytometry): U251 cells.
Immunogen
Recombinant human Factor H/CFH fragment (Asn115–Ala998), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes complement factor H as secreted and also located in the SUBCELLULAR LOCATION:. Tissue expression noted by UniProt (human): Expressed in the retinal pigment epithelium (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
