一般說明

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.

應用

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.

生化/生理作用

绝经前卵巢分泌的主要雌激素。雌激素通过调节基因转录并因此调节蛋白质合成来指导胚胎发生和青春期女性表型的发展。 它还诱导促性腺激素的产生,进而诱导排卵。 暴露于雌二醇会增加乳腺癌的发生率和增殖。

分析報告

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

其他說明

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

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
