This monoclonal antibody (B72.3) to tumor-associated glycoprotein recognizes a tumor-associated oncofetal antigen (TAG-72) expressed by a wide variety of human adenocarcinomas. This antigen is expressed by most invasive ductal breast, colonic, pancreatic, gastric, esophageal, lung, ovarian and endometrial adenocarcinomas. This antigen is also expressed on normal secretory endometrium, but not on other normal tissues.
- A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen type
- One (1) unbaked, unstained slide for H&E staining (required) and two to three (2-3) positively charged unstained slides (all cut at 4-5 microns) for each test/antibody ordered
- Block and slide identifiers should be clearly written and match exactly with the specimen ID and specimen labeling as noted on the requisition.
Use cold pack for transport. Make sure cold pack is not in direct contact with specimen.
