Estrone acetate (Hogival) is an estrogen derivative and an estrogen receptor (ER) activator. It promotes mammary gland development, stimulates pituitary prolactin secretion, and induces the proliferation and activation of lactotrophs (e.g., by reducing prolactin storage granule size while increasing rough endoplasmic reticulum and Golgi apparatus volume density). Estrone acetate holds potential for endocrine research, particularly in studying estrogen's effects on pituitary function, prolactin regulation, and mammary tumor models.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
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.
