閉経前に卵巣から分泌される主要なエストロゲンです。
閉経前に卵巣から分泌される主要なエストロゲンです。エストロゲンは、遺伝子転写によるタンパク合成を調節することにより、胚発生期や思春期におけるメス表現型の発達を誘導します。また、ゴナドトロピン産生を促すことにより排卵を誘発します。エストラジオールへの曝露は乳癌の発生率や増殖を増強します。

Analysis Note

These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.

Application

Estradiol may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Estradiol is a steroid hormone present naturally in the human body. The availability of this hormone is quintessential in older women as it is a determinant of menopausal syndromes. It is utilized for the prevention of cardiovascular diseases.

Splicing reactions generally combine high speed with accuracy. However, some of the pre-mRNAs escape the nucleus with a retained intron. Intron retention can control gene expression and increase proteome diversity. We calculated the escape rate for the yeast PTC7 intron
