IRX4 Antibody, Biotin conjugated

Overview

This polyclonal anti-IRX4 antibody raised in Rabbit, conjugated with Biotin, tested in ELISA. Designed to detect IRX4 in Human for others research.

Key elements and design rationale

• Immunogen: Recombinant Human Iroquois-class homeodomain protein IRX-4 protein (287-363AA) — 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.
• Biotin: Streptavidin/avidin amplification; block endogenous biotin in biotin-rich samples.

Biological background

IRX4 (also: Homeodomain protein IRXA3, Iroquois homeobox protein 4, Iroquois-class homeodomain protein IRX-4, Iroquoisclass homeodomain protein IRX4, Irx4, IRX4_HUMAN, IRXA3) — studied in Human systems. Expression, localization, and PTMs vary across cell types and disease states. Consult UniProt, NCBI Gene, and primary literature for current IRX4 annotation relevant to others.

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.

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).
