EPCAM Antibody

Overview

This polyclonal anti-EPCAM antibody raised in Rabbit, tested in ELISA, WB, IHC, IF. Designed to detect EPCAM in Human, Rat for tags & cell markers research.

Key elements and design rationale

• Immunogen: Recombinant Human Epithelial cell adhesion molecule protein (24-265AA) — 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.

Expression, localization, and PTMs vary across cell types and disease states. Consult UniProt, NCBI Gene, and primary literature for current EPCAM annotation relevant to tags & cell markers.

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.
• IF: Subcellular localization in fixed cells/sections; optimize fixation.

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, Rat; extrapolation requires validation.

This product is a polyclonal antibody purified from rabbit antiserum.
