Overview
This is a polyclonal anti-Fgf23 antibody raised in Rabbit, with confirmed utility in ELISA, WB. Designed to detect Fgf23 in Rat, supporting researchers in signal transduction contexts.
Key elements and design rationale
- Immunogen: Recombinant Rat Fibroblast growth factor 23 protein (25-251AA) — determines the epitope region recognized; confirm epitope compatibility with your sample preparation and expected PTMs.
- Host (Rabbit): Requires anti-rabbit-IgG secondary reagents. Mismatched secondaries result in no signal. Consider host species when multiplexing.
- Polyclonal: Recognizes multiple epitopes — robust signal across varied preparations, with inherent lot-to-lot variability. Isotype controls and lot qualification recommended.
- Isotype (IgG): Secondary antibodies and isotype controls must match IgG from Rabbit. Relevant for multiplexing and Protein A/G compatibility.
- Purification (Protein G purification): Reduces non-specific immunoglobulin populations, improving signal-to-noise in quantitative immunoassay formats.
Biological background
Fgf23 (also known as Fgf23Fibroblast growth factor 23, FGF-23) is a protein studied in Rattus norvegicus (Rat) systems. Expression levels, subcellular localization, and post-translational modifications vary across cell types, tissues, and disease states — factors that influence antibody-based detection outcomes. Researchers are encouraged to consult UniProt, NCBI Gene, and primary literature for current annotation of Fgf23 biology relevant to signal transduction.
Common research applications
- ELISA: Sandwich or indirect ELISA quantifies soluble/secreted target in biological fluids or cell culture supernatants.
- WB: Western blot confirms target MW and detects isoforms/fragments under denaturing conditions.
Notes for experimental interpretation
- Isotype controls: Include IgG from Rabbit at equivalent concentration to assess non-specific background.
- Cross-reactivity/isoforms: Polyclonal preparations may cross-react with related proteins or isoforms — validate with siRNA KD, KO lysate, or recombinant protein controls.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) may influence performance; pilot dilution linearity and spike-recovery experiments before full quantitative studies.
- Species reactivity: Confirmed for Rat; extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
Fgf23 is a protein target in Rat biology. This polyclonal antibody raised in Rabbit detects Fgf23 and is validated for ELISA, WB applications.
This antibody is reported reactive against Rat. Immunogen derived from Rattus norvegicus (Rat). Cross-reactivity with unlisted species should not be assumed — contact us or consult the datasheet for homology data.
Supplier reports performance in ELISA, WB. Dilution optimization, blocking, and appropriate controls are required per format. Contact BioHippo for recommended working concentrations.
This non-conjugated (IgG) antibody requires a secondary anti-rabbit IgG conjugated to HRP, AP, fluorophore, or biotin. Match the secondary to the host (Rabbit) and isotype (IgG).
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — lysate/cell line expressing Fgf23; (3) Negative control — siRNA KD or KO sample to confirm specificity; (4) Dilution linearity — verify proportional signal decrease for quantitative applications.
