ProteinExtTM Phosphatase Inhibitor Cocktail, EDTA-free (100×) is a ready-to-use mixture of six protease inhibitors (AEBSF, Aprotinin, Bestatin, E-64, Leupeptin, and Pepstatin A)that has been optimized to protect proteins from being digested by endogenous proteases, including serine protease, cysteine protease, aminopeptidase and aspartic acid protease. This cocktail is suitable for use in protein purification, Western Blot, Co-IP, ChIP, protein kinase activity assay, etc.The cocktail does not contain EDTA (a metalloprotease inhibitor), which is incompatible with some downstream applications (i.e. protein assays, 2D electrophoresis, etc.).
• All-in-one format: a mixture of broad-spectrum protease inhibitors to prevent proteolytic degradation.
• Ready to use: no need to thaw and dissolve the cocktail, just use directly.
• Compatibility: compatible with most of protein lysis buffers composed of detergent and do not interfere with protein quantitation.
