詳細
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. L-Aspartic acid is a non-essential amino acid. It is involved in the Urea cycle, Krebs cycle and in DNA metabolism. L-Aspartic acid is used as a cell culture media component for the commercial biomanufacture of therapeutic recombinant proteins and monoclonal antibodies.
アプリケーション
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.

Drug molecules should remain uncharged while traveling through the body and crossing membranes and should only adopt charged state upon protein binding, particularly if charge-assisted interactions can be established in deeply buried binding pockets. Such strategy requires careful pKa design
