Used in biomedical research to quantify human platelet-derived growth factor AA (PDGF-AA) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study PDGF-AA's role in cell proliferation, wound healing, tissue regeneration, and angiogenesis. It is widely applied in studies related to cardiovascular diseases, fibrosis, and cancer, where PDGF signaling pathways are involved. The assay provides a sensitive and specific method for monitoring changes in PDGF-AA expression under experimental or clinical conditions, supporting both basic science and drug development efforts.
