Product nameEstradiol benzoate, Estradiol analog
DescriptionEstradiol analog which binds to the human, murine and chicken ERα with IC50 of 22-28 nM.
- E2 Benzoate
Estradiol analog which contains a benzyl ester at the C-3 position. Binds to the human and murine estrogen receptor α (ERα), and chicken ER with IC50 values in the range of 22-28 nM. This reflects a 6-10 fold reduction in binding affinity compared to estradiol. Used in combination with a progestin to induce estrus in domestic livestock.
Chemical name[(8R,9S,13S,14S,17S)-17-Hydroxy-13-methyl-6,7,8,9,11,12,14,15,16,17-decahydrocyclopenta[a]phenanthren-3-yl] benzoate
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
