Used in research and development for studying cell signaling pathways related to stem cell factor receptor (c-Kit) activity. Plays a role in immunoassays and protein interaction studies due to the Fc tag, which allows for easy detection and purification. Applied in therapeutic target validation, especially in cancers and disorders involving c-Kit mutations, such as gastrointestinal stromal tumors (GIST) and certain leukemias. Supports antibody development and binding assays by serving as a soluble recombinant receptor.
