Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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.

Wird für die Denaturierung von Proteinen und als mildes Mittel zur Solubilisierung unlöslicher oder denaturierter Proteine?? verwendet. Nützlich für die Renaturierung von Proteinen aus Proben, die bereits mit 6 M Guanidinchlorid vergällt sind, wie z.B. Einschlüssen. Kann mit Guanidin-hydrochlorid und Dithiothreitrol (DTT) für die Rückfaltung von denaturierten Proteinen in ihre native oder aktive Form eingesetzt werden.

Hinweis zur Analyse

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

Sonstige Hinweise
