CLDN3 Antibody

Overview

This polyclonal anti-CLDN3 antibody raised in Rabbit, tested in ELISA, WB, IHC. Designed to detect CLDN3 in Human for signal transduction research.

Key elements and design rationale

• Immunogen: Recombinant Human Claudin-3 protein (181-220AA) — 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.

Biological background

CLDN3 (also: C7orf1, Claudin-3, Claudin3, CLD3_HUMAN, CLDN 3, Cldn3, Clostridium perfringens enterotoxin receptor 2, CPE R2, CPE receptor 2, CPE-R 2, CPE-receptor 2, CPETR 2, CPETR2, HRVP 1, HRVP1, Rat ventral prostate 1 like protein, Rat ventral prostate.1 protein homolog, RVP1, Ventral prostate.1 like protein, Ventral prostate.1 protein homolog) — studied in Human systems. Expression, localization, and PTMs vary across cell types and disease states. Consult UniProt, NCBI Gene, and primary literature for current CLDN3 annotation relevant to signal transduction.

Common research applications

• ELISA: Quantify soluble target; ensure samples within the linear detection range.
• WB: Confirms MW, distinguishes isoforms under denaturing conditions.
• IHC: Tissue expression in FFPE/frozen sections; optimize antigen retrieval.

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.
