Application
- fractionnement cellulaire
- comme supplément pour l'extraction de protéines nucléaires
- inhibition de la cholestérol estérase (CE) et de la pseudocholinestérase (PCE)
- prélèvement de sang avant centrifugation pour la quantification du taux d'ANP plasmatique
Voici quelques-uns des caractéristiques et avantages observés :
