Scientific Data Images for Human TROP‑2 Biotinylated Antibody

TROP-2 antibody in Human Cervical Cancer Tissue by Immunohistochemistry (IHC-P).

TROP-2 in Human Cervical Cancer Tissue.

TROP-2 was detected in immersion fixed paraffin-embedded sections of human cervical cancer tissue using Goat Anti-Human TROP-2 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF650) at 3 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (brown; Catalog # VC004) and counterstained with hematoxylin (blue). Specific staining was localized to cell membrane in cancer cells. View our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: TROP-2

Human TROP-2, also called tumor associated calcium signal transducer 2 (TACSTD2), GA733-1, gp50 and T16, is a type I cell surface glycoprotein that is highly expressed on human carcinomas. It was originally identified as an antigen present on human gastrointestinal tumors and is the second of two members of this family. The other family member is GA733-2, also called EpCAM, TROP-1, 17-1A, gp40 and KSA. The TROP-2 gene is unique in that it contains no introns. A study of these two genes suggested that TROP-2 was the result of a retroposition of the EpCAM gene. TROP-2 and EpCAM share approximately 49% amino acid identity and approximately 67% similarity. Human and mouse TROP-2 share 87% similarity. The human TROP-2 protein consists of a putative 26 amino acid (aa) signal sequence, a 248 aa extracellular domain, a 23 aa transmembrane region and a 26 aa cytoplasmic domain. TROP-2 is capable of transducing an intracellular calcium signal and may play a role in tumor growth. It also has adhesive functions.
