The specific method used to test this material for protease activity is considered proprietary. However, it is based on the enzymatic cleavage of FITC-Casein. See the link below to review the FITC-Casein Enzymatic Assay to demonstrate the principle of this method.

General description
- Quantification des protéines (comme étalon)
- Immunochimie (comme agent de blocage)
- Culture cellulaire (comme nutriment)
La très faible teneur ou l'absence de protéases de cette BSA est spécifiquement évaluée et testée. Cette BSA dépourvue de protéases peut notamment être utilisée dans les applications suivantes :
- Dosages enzymatiques
- Tests utilisant des protéines
- Techniques sensibles aux protéases, dont :
b) Hybridation d'acides nucléiques
c) Dosages radio-immunologiques (RIA)
Application
Biochem/physiol Actions
Features and Benefits
- Fractionnement par choc thermique
- Absence de protéases
- Quasi-absence de globulines

Is Product A3059, Albumin from bovine serum (BSA), acetylated to inactivate nucleases?
1 answer-
A3059 is not acetylated. We do not test for the presence of nucleases. Acetylated BSA products would be B2518 or B8894.

Is Product A3059, Albumin from bovine serum (BSA), suitable for use as a blocking agent in immunoblotting?
1 answer-
We have not tested A3059 for specific use in immunoblotting as a blocking agent, in quality control. However, A3059 is considered to be essentially gamma-globulin free, which makes this more potentially useful in blotting experiments, by reducing a potential source of background. The Technical Bulletin states that "Globulin free albumins are suitable for use in applications where no other proteins should be present".
