Anti-TSPAN8 Antibody is a humanized monoclonal antibody that binds specifically to TSPAN8 (Tetraspanin-8) with high affinity. This product effectively inhibits TSPAN8-mediated cancer cell stemness and distant metastasis. By blocking TSPAN8 signaling, the antibody downregulates the expression of stemness markers and attenuates the invasive capacity of tumor cells, serving as a pharmacological tool for researching the progression of colorectal cancer and other malignancies.
