TAG-72 antibody

Catalog No. ABIN3026693

Product Details anti-TAG-72 Antibody

Target: TAG-72 (Temporarily Assigned Gene Name Family Member (TAG-72))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This TAG-72 antibody is un-conjugated

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

Characteristics: This antibody recognizes an oncofetal antigen of 220 kDa, identified as a tumor-associated glycoprotein (TAG-72) with properties of a mucin. TAG-72 is usually expressed by adenocarcinomas, but is negative in mesotheliomas. Studies have reported that this antibody has 80 % sensitivity and 93 % specificity for pulmonary adenocarcinoma. Therefore, TAG-72 is a useful marker to distinguish between mesothelioma and adenocarcinoma. However, false positive reactions can occur so results must be interpreted with the utmost caution. This antibody may be useful in the differentiation of non-small cell carcinomas from small cell carcinomas of the lung. The combined use of TAG-72 antibody with a GCDFP-15 antibody is valuable in the diagnosis of apocrine carcinoma.

Purification: Protein G affinity chromatography

Immunogen: Recombinant human TAG-72 protein was used as the immunogen for this antibody.

Clone: TAGP-4

Isotype: IgG1 kappa
