Applications/Dilutions

• Dilutions:
  • Immunohistochemistry-Paraffin 1-2ug/ml
• Application Notes: Immunohistochemistry-Paraffin: 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes. Optimal dilution for a specific application should be determined.

Packaging, Storage & Formulations

Background

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. 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-).
