Used in immunological research to study the Delta-like ligand 3 (DLL3) protein expression and its role in Notch signaling pathways in non-human primate models. Facilitates the development and testing of targeted cancer therapies, especially for small cell lung cancer and other neuroendocrine tumors where DLL3 is overexpressed. Serves as a critical reagent in assay development, protein-protein interaction studies, and antibody validation due to its high purity and functional activity. The His Tag allows for easy detection and purification in experimental settings, making it valuable in preclinical research involving Cynomolgus or Rhesus Macaque as translational models.
