Used in research and diagnostic applications to detect and quantify melanotransferrin (also known as CD228), a protein associated with melanoma and other cancers. This reference antibody is particularly valuable in immunoassays, flow cytometry, and immunohistochemistry to identify tumor cells expressing CD228, aiding in cancer biomarker studies and therapeutic development. It supports the investigation of iron transport mechanisms in malignant cells and helps evaluate the specificity of anti-CD228 targeting agents in oncology research.
