Descripción

Descripción general

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.

Aplicación

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.

Utilizada para la desnaturalización de proteínas y como suave agente de solubilización para las proteínas insolubles o desnaturalizadas. Útil para la renaturalización de proteínas de muestras ya desnaturalizadas con cloruro de guanidina 6 M como los cuerpos de inclusión. Puede utilizarse con clorhidrato de guanidina y ditiotreitol (DTT) en el repliegue de las proteínas desnaturalizadas a su forma nativa o activa.

Nota de análisis

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