Used in research and development for studying cell growth, proliferation, and tissue repair mechanisms. Plays a role in angiogenesis studies and is utilized in assays to evaluate receptor binding and signal transduction pathways involving PDGF receptors. Commonly applied in protein-protein interaction experiments due to the hFc tag, which allows for easy detection and purification. Supports development of therapeutics targeting fibrosis, wound healing, and certain cancers by serving as a reference protein in biological activity assessments.
