**Semantic type:** Amino Acid, Peptide, or Protein|Indicator, Reagent, or Diagnostic Aid|Pharmacologic Substance

**Definition:** A radioimmunoconjugate of a murine whole immunoglobulin G monoclonal antibody MAb-170 labeled with Technetium 99m (Tc-99m). MAb-170, originally raised against a carbohydrate epitope (a synthetic Thomsen-Friedenreich antigen), has been found to have panadenocarcinoma affinity, including adenocarcinomas of breast, fallopian tube, colon, endometrium, prostate, bladder, liver, lung, and ovary. Tc-99m MAb-170 delivers gamma emission Tc-99m nuclide directly to adenocarcinoma tissues, thereby this agent may be used for diagnostic or imaging purposes.

**Synonyms:** - Tc99m MOAB 170 - Technetium Tc 99m Monoclonal Antibody 170
