Description

• Protease Inhibitor Cocktail protects protein extracts from aminopeptidases, metalloproteases, and serine, cysteine, and aspartic acid proteases. It is supplied as a 100X stock solution of protease inhibitors dissolved in DMSO and a 100X stock solution of EDTA dissolved in water, pH 8.0. Ab271306 is a general-purpose reagent suitable for protease inhibition during protein extraction from mammalian tissues and cells, yeast and fungal cells, and bacteria.
• ab271306 contains the chelating agent EDTA for improved protection against metalloproteases. It should therefore not be added to samples intended for subsequent analysis by techniques that are incompatible with EDTA, such as isoelectric focusing and metal affinity column separations.
