Genistein Specification

 Biological effects of Genistein (CAS NO.446-72-0) are some isoflavones act as antioxidants to counteract damaging effects of free radicals in tissues; Genistein protects against pro-inflammatory factor-induced vascular endothelial barrier dysfunction and inhibits leukocyte-endothelium interaction, thereby modulating vascular inflammation, a major event in the pathogenesis of atherosclerosis and it makes some cells more sensitive to radio-therapy.
