Used in research and development of targeted cancer therapies, particularly in colorectal and pancreatic cancers where TSPAN8 is overexpressed. This antibody serves as a reference tool for detecting and quantifying TSPAN8, a tetraspanin protein involved in tumor cell migration, invasion, and metastasis. It enables validation of diagnostic assays and supports the development of therapeutic antibodies and immunoconjugates. Due to its specific binding properties, it is also employed in flow cytometry, immunohistochemistry, and Western blotting to study TSPAN8 expression patterns in tumor tissues and cell lines. Its role in the INSERM patent highlights its importance in early-stage biopharmaceutical innovation targeting epithelial cancers.
