Recombinant Human Fetuin A Protein is a major plasma protein and a member of the cystatin superfamily of protease inhibitors. Human Fetuin A is expressed by hepatocytes, the principal cell source, and by monocyte/macrophages. It is highly expressed in embryonic cells and adult hepatocytes, and is expressed to a lesser extent in monocytes/macrophages. It is a negative acute-phase protein with normal circulating levels in adults (300-600 μg/mL), which fall significantly (30-50%) during injury and infection. Human Fetuin A inhibits both insulin receptor autophosphorylation and undesirable calcification . It also can act as a natural antagonist against specific TGF-β and BMP signaling proteins.
Expression host is Human HEK293 cells

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
