Used to measure levels of platelet-derived growth factor BB (PDGF-BB) in human biological samples such as serum, plasma, or cell culture supernatants. This assay is commonly applied in research settings to study conditions involving cell proliferation, wound healing, angiogenesis, and tissue repair. It is also used in cancer research, as PDGF-BB is associated with tumor growth and progression. The kit enables accurate quantification of PDGF-BB concentrations, supporting studies in cardiovascular diseases, fibrosis, and regenerative medicine.
