General description

β-estradiol is a natural human estrogen. It is vital for the growth of breast and reproductive epithelia, maturation of long bones and development of secondary sexual characteristics.[1] Estradiol is produced by immature germ cells, spermatozoa, Leydig cells and Sertoli cells.[2] β-estradiol acts as a menopausal hormones. It is involved in replacement therapy for female hypogonadism or primary ovarian failure. Reduced levels of β-estradiol are linked to heart disease and osteoporosis.[1] Estradiol plays a critical role in proliferation, modulation of ion transport and control of apoptosis in Sertoli cells. It maintains sperm concentration, motility and morphology.[2]

Application

β-estradiol has been used:
  • to culture differentiated adipocytes[3]
  • for estradiol treatment in rats[4]
  • for oocyte maturation in vitro[5]
β-Estradiol is used to study cell differentiation and transformations (tumorigenicity). This product is not recommended for use in binding assays.

Packaging

Package size based on estradiol

Other Notes

Contains 40-55 mg estradiol per gram of solid; balance 2-hydroxypropyl-β-cyclodextrin.

Questions

1–4 of 4 Questions  
  1. what is the molecular weight of E-4389 product?

    1 answer
    1. This is a dual-component product. A single molecular weight does not apply. The molecular weight of the B-estradiol is 272.38 grams per mol, and the molecular weight of the 2-hydroxypropyl-β-cyclodextrin is 1396 grams per mol. The package size of 100 mg is in reference to the B-Estradiol. This product contains 40 - 50 mg per gram solid. The lot-specific B-estradiol content is reported in the Certificate of Analysis.

  2. What is the storage stability of E4389, β-Estradiol - Water Soluble (25 mg/mL complex) in distilled water at 4C, -20C, or -80C?

    1 answer
    1. This product is stable for 6 months at -20°C in a non-defrosting freezer after solubilizing in distilled water. There is no stability data for this product at 4°C or -80°C.

  3. How do I calculate the molarity of product E4389, β-Estradiol - Water Soluble?

    1 answer
    1. Product E4389 (β-Estradiol-Water Soluble) is a complex of β-Estradiol and cyclodextrin. Cyclodextrin is used to aid in the solubility of β-Estradiol into water. In order to prepare a molar solution of β-Estradiol you will have to base it on the β-Estradiol content in the solution and not the entire complex.
