TFF2 Antibody (366508) [Unconjugated]

TFF2 was detected in immersion fixed paraffin-embedded sections of human stomach using Mouse Anti-Human TFF2 Monoclonal Antibody (Catalog # MAB4077) at 1.7 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to gastric glands.

Background

Trefoil Factor 2 (TFF2), previously called spasmolysin, is one of three trefoil peptides secreted by epithelial cells that line mucus membranes. Trefoils contribute to protection and repair of the gastrointestinal tract. TFF2 is secreted by epithelia of the basal gastric glands and duodenal Brunner’s glands, but is also found in spleen, thymus and lung and may modulate leukocyte recruitment to sites of inflammation in these tissues. The 129 amino acid (aa) human TFF2 contains two trefoil structures formed by intramolecular disulfides and shows 82% aa identity with mouse TFF2.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
