Description and Uses

Genistin is a natural isoflavone isolated from legumes, including soy and kudzu. It is a phytoestrogen, as it stimulates the growth of estrogen-dependent human breast cancer cells in vivo. Like other isoflavones, genistin promotes the proliferation of bone marrow stromal cells and osteoblasts and suppresses bone turnover. It also increases bone formation in collagen matrix in vivo.

Genistin has been used for immune reactivity against influenza viruses in vitro and as an internal standard in isoflavones quantification.
