General tips:For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging:1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition:Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Biological Activity of beta-Estradiol
Description | Estradiol, or more precisely, 17β-estradiol, is a human sex hormone and steroid, and the primary female sex hormone. Beta-estradiol has been considered to be a neurotrophic agent, beta-estradiol at a dose of 0.25 microg/day prevents ischemia-induced learning disability and neuronal loss at early stages after transient forebrain ischemia, possibly via a receptor-mediated pathway without attenuating free radical neurotoxicity. |
Targets | LDL |
In vitro |
β-Estradiol results in a proprotein convertase subtilisin/kexin type 9-dependent increase in low-density lipoprotein receptor levels in human hepatic HuH7 cells.[Pubmed: 25913303] FEBS J. 2015 Jul;282(14):2682-96. The lower risk of coronary artery disease in premenopausal women than in men and postmenopausal women implicates sex steroids in cardioprotective processes. beta-Estradiol upregulates liver low-density lipoprotein receptor (LDLR), which, in turn, decreases circulating levels of low-density lipoprotein, which is a risk factor for coronary artery disease. Conversely, LDLR protein is negatively regulated by proprotein convertase subtilisin/kexin type 9 (PCSK9). |
In vivo |
Gonadal status-dependent effects of in vivo β-estradiol administration to female rats on in vitro epileptiform activity induced by low [Mg2+]? in combined hippocampus-entorhinal cortex slices.[Pubmed: 24113171] Epilepsy Res. 2013 Dec;107(3):297-301. There are controversial data regarding estrogen effects on neuronal excitability. |
Protocol of beta-Estradiol
Animal Research |
Beta-estradiol protects hippocampal CA1 neurons against transient forebrain ischemia in gerbil.[Pubmed: 9527626] Neurosci Res. 1997 Dec;29(4):345-54. beta-Estradiol has been considered to be a neurotrophic agent, but its in vivo effect on gerbils with transient forebrain ischemia has not yet been demonstrated. |
