Used in immunological research to study platelet-derived growth factor signaling in non-human primate models. Enables detection and quantification of PDGFB interactions in cell culture and tissue samples. Supports development of therapeutic antibodies by serving as a binding target in assay systems. Facilitates investigation of vascular development and fibrosis mechanisms in preclinical studies. The Fc tag allows for easy detection and purification using anti-Fc reagents.
