4.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 80 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 4-Hydroxytamoxifen (Afimoxifene) is the active metabolite of tamoxifen and a selective estrogen receptor (ER) modulator that is widely used in the therapeutic and chemopreventive treatment of breast cancer. It activates on-target modification frequency for intein-Cas9 variants.
In vitro 4-OHT is a potent activator of ER and has been shown to have a higher affinity for estrogen receptors compared to tamoxifen. It has significant dose and time-dependent direct effects to alter the contractile function of isolated adult rat cardiac myocytes[1]. 4-HT activates on-target modification frequency for intein-Cas9 variants [3].
