Tumor-associated glycoprotein (TAG-72) is an oncofetal antigen with properties of a mucin. About 60% of carcinoma patients express TAG-72 in their sera.

Host Species: Mouse

Clone: B72.3

Isotype: IgG1/κ

Species Reactivity: Human, Cow, Dog, Hamster and Rat. Others not known.

Epitope: Mucin-carried-sialylated-Tn epitope

Immunogen: Membrane-enriched fraction of a human breast carcinoma liver metastasis

Molecular Weight: >1000kDa

Positive Control: Breast or lung CA

Cellular Localization: Cell surface and cytoplasmic. The majority of human adenocarcinomas including colorectal, pancreatic, gastric, ovarian, endometrial, mammary, and non-small cell lung cancer display some cell populations that are positive for Ab-1 staining. Weak or no reactivity has been observed with most cell types of normal adult tissue excepting the secretory endometrium. Ab-1 is reportedly useful in distinguishing pulmonary adenocarcinomas (B72.3+) from pleural mesotheliomas (B72.3-).

Recommended for:

  • Immunohistochemistry (Formalin/paraffin)
  • Flow Cytometry
  • Radioimaging
