Used to quantitatively measure human BMP-4 levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is widely applied in research settings to study bone formation, tissue development, and cellular differentiation processes. It supports investigations in regenerative medicine, osteoporosis, and stem cell research by providing accurate and reliable detection of BMP-4 concentration. The assay helps assess the role of BMP-4 in signaling pathways and disease mechanisms, particularly in conditions involving abnormal bone growth or tissue repair.
