General description
SIGMAFAST™ Protease Inhibitor Cocktail Tablets, EDTA-Free is a water-soluble tablet formulation designed to inhibit serine, cysteine, aspartic and metalloproteases. The tablets contain no strong metal chelators, such as EDTA, and are compatible with sample processing by immobilized metal affinity chromatography (IMAC). The tablets also contain a unique, proprietary formulation that includes a pepstatin A salt for additional protection.
Application
The broad specificity of SIGMAFAST™ Protease Inhibitor Cocktail Tablets makes them suitable for use in the purification of histidine-tagged proteins and as a general-purpose protease inhibitor cocktail. The tablets can also be used as components of buffers for cell lysis, and have been optimized and tested for use with HIS-Select® media.
Biochem/physiol Actions
Inhibits serine, cysteine, aspartic, and metalloproteases.
Features and Benefits
EDTA-Free: Contains no strong metal chelators, such as EDTA, which might interfere with IMAC processing.
Pepstatin A: Contains a unique, proprietary formulation that includes a pepstatin A salt for additional protection not normally obtained in a tablet format.
Broad Specificity: Inhibits serine, cysteine, aspartic, and metalloproteases, providing broad protection for protein samples.
High Yield: One tablet makes 100 mL of cocktail, and is recommended for the inhibition of the proteases present in a maximum of 20 g of cell mass in 100 mL of extract.
Long Stability: The tablets are stable as supplied for at least 2 years at 2–8 °C, and the reconstituted protease inhibitor solution (1´ or 10´) is stable for at least 2 weeks at 2–8 °C.

How should I dissolve Product No. S8830, SIGMAFAST™ Protease Inhibitor?
1 answer-
You can dissolve the product in 100 ml of water to make a 1X solution. You can make a 10X stock solution using 10 ml of water and then dilute 1:10 for use. Concentrations greater than 1X may appear slightly hazy. This will not affect the performance of the protease inhibitors.
