TFF1 antibody (C-Term)

Catalog No. ABIN3025060

Product Details anti-TFF1 Antibody

Target: TFF1 (Trefoil Factor 1 (TFF1))

Binding Specificity: C-Term

Reactivity: Human, Monkey

Host: Mouse

Clonality: Monoclonal

Conjugate: This TFF1 antibody is un-conjugated

Application: Immunofluorescence (IF), Flow Cytometry (FACS), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Characteristics: It recognizes a polypeptide of 6.5 kDa, identified as pS2 estrogen-regulated protein. Its epitope is located in the c-terminus of human pS2 protein. pS2 is a trefoil peptide. Trefoil peptides are protease resistant molecules secreted throughout the gut that play a role in mucosal healing. These peptides contain three intra-chain disulfide bonds, forming the trefoil motif, or P-domain. pS2 is known to form dimers and this dimerization is thought to play a role in its protective and healing properties. About 60 % of breast carcinomas are positive for pS2. Staining is cytoplasmic, often with localization to the Golgi apparatus. pS2 is shown to be localized in normal stomach mucosa, gastric fluid, goblet cells in the colon and small intestine, and in ulcerations of the gastrointestinal tract. Several studies have shown that pS2 is primarily expressed in estrogen receptor-positive breast tumors and it may define a subset of estrogen-dependent tumors that displays an increased likelihood of response to endocrine therapy.

Purification: Protein G affinity chromatography

Immunogen: A C-terminus peptide was used as the immunogen for the TFF1 antibody.

Clone: TFF1-1091

Isotype: IgG1 kappa

Application Details

Application Notes: Optimal dilution of the TFF1 antibody should be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10  mM Citrate buffer,  pH 6.0, for 10-20 min followed by cooling at RT for 20 min.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.\. Flow Cytometry: 0.5-1 μg/million cells in 0.1ml,Immunofluorescence: 0.5-1 μg/mL,Immunohistochemistry (FFPE): 0.5-1 μg/mL for 30 min at RT (1),Prediluted format: incubate for 30 min at RT (2)

Restrictions: For Research Use only
