0.34mg/ml Taking the 1 mL working solution as an example, add 50 μL of 6.8 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.7mg/ml Taking the 1 mL working solution as an example, add 50 μL of 54 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Genistein, a phytoestrogen found in soy products, is a highly specific inhibitor of protein tyrosine kinase (PTK) which blocks the mitogenic effect mediated by EGF on NIH-3T3 cells with IC50 of 12μM.
Targets
EGFR [1] topo II [1]
In vitro

Genistein is an ATP competitive inhibitor. Genistein inhibits tyrosine phosphorylation in isolated enzyme and receptor preparations and in whole cells including platelets, lymphocytes and a variety of cultured cells. It also inhibits EGF-stimulated phosphorylation in cultured cells as well as inhibition of Topo II (topoisomerase II). Genistein inhibits EGF-stimulated tyrosine phosphorylation in cultured A431 epidermoid carcinoma cells. Inhibition is competitive with ATP and noncompetitive with substrate. [1] Genistein blocks the mitogenic effect mediated by EGF and thrombin on NIH-3T3 cells.[2] Genistein also acts as an agonist at the GPR30 receptor and binds to PPARγ and estrogen receptors. Genistein also binds to PPARγ, acting as an agonist at this receptor with Ki of 5.7 μM. [3]
In vivo

Genistein has chemopreventive effects on breast, prostate, and other endocrine-dependent tumors in adult animals. Genistein in the diet reduced the incidence of poorly differentiated prostatic adenocarcinomas in a dose-dependent manner and down-regulated androgen receptor, estrogen receptor-alpha, epidermal growth factor receptor, and extracellular signal-regulated kinase-1 but not estrogen receptor-beta and transforming growth factor-alpha mRNA expressions. Dietary genistein protects against mammary and prostate cancers by regulating specific sex steroid receptors and growth factor signaling pathways.[4] Genistein combined with prostate tumor irradiation causes greater inhibition of primary tumor growth and increases control of spontaneous metastasis to para-aortic lymph nodes, increasing mouse survival. Paradoxically, treatment with genistein alone increases metastasis to lymph nodes. [5]
