Used in research and development for studying platelet-derived growth factor receptor beta (PDGFRβ) signaling pathways involved in cell growth, proliferation, and survival. Commonly applied in immunoassays and protein-protein interaction studies due to the Fc tag, which allows detection and purification using anti-Fc antibodies. Supports investigation of diseases involving PDGFRβ dysregulation, such as fibrosis, cancer, and certain cardiovascular conditions. Also used as a capture or detection reagent in ELISA and flow cytometry. The Fc tag enables dimerization, mimicking natural receptor clustering, enhancing its utility in functional studies.
