Overview
This polyclonal anti-CFI antibody raised in Rabbit, conjugated with HRP, tested in ELISA. Designed to detect CFI in Human for immunology research.
Key elements and design rationale
- Immunogen: Recombinant Human Complement factor I protein (239-316AA) — determines epitope; confirm sample prep compatibility.
- Host (Rabbit): Requires anti-rabbit-IgG secondary matching isotype IgG.
- Polyclonal: Multiple epitopes = robust signal; lot-to-lot variability — include controls.
- Isotype (IgG): Match secondary, Protein A/G, and isotype controls to IgG.
- Purification (Protein G purification): Enriches Ig classes; reduces non-specific background.
- HRP: Direct detection (TMB/ECL); quench endogenous peroxidase in tissue assays.
Biological background
CFI (also: AHUS3, ARMD13, C3b INA, C3b inactivator, C3B/C4B inactivator, C3BINA, CFAI_HUMAN, Cfi, Complement component I, Complement control protein factor I, Complement factor I, Complement factor I heavy chain, Complement factor I light chain, F1, factor I, FactorI, FI, I factor, IF, KAF, Konglutinogen activating factor, Light chain of factor I, OTTHUMP00000219728, OTTHUMP00000221928) — studied in Human systems. Expression, localization, and PTMs vary across cell types and disease states. Consult UniProt, NCBI Gene, and primary literature for current CFI annotation relevant to immunology.
Common research applications
- ELISA: Quantify soluble target; ensure samples within the linear detection range.
Notes for experimental interpretation
- Isotype controls: IgG from Rabbit at equivalent concentration.
- Cross-reactivity: Polyclonal: validate with KO/KD controls.
- Matrix effects: Verify dilution linearity in your sample matrix.
- Reactivity: Confirmed for Human; extrapolation requires validation.
This product is a polyclonal antibody purified from rabbit antiserum.
CFI is a protein studied in Human biology. This polyclonal antibody raised in Rabbit detects CFI in ELISA applications, IgG isotype.
Reported reactive against Human. Immunogen from Human. Cross-reactivity with untested species requires empirical confirmation.
Reported for ELISA. Optimize dilution/blocking per application. Consult datasheet for working concentrations.
HRP: direct detection (TMB/ECL); quench endogenous peroxidase in tissue assays.
(1) Isotype control: IgG from Rabbit; (2) Positive control: lysate/cell line expressing CFI; (3) Negative control: siRNA KD or KO; (4) Dilution linearity in your sample matrix.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
