A proteolytic fragment or domain of a protein may crystallize more readily or form better diffracting crystals than the intact protein.1-8

Proteases can be used to generate small, active fragments or domains of the target protein for crystallization.9 The fragment or domain can be used directly for crystallization experiments. Or the proteolytic sample analyzed by gel electrophoresis and/or mass spectrometry for mass and sequence for subsequent cloning, expression, purification and crystallization. Using proteolysis to enhance sample crystallization, the current overall success rate for yielding a deposited crystal structure is currently better than 12%.3

Proti-Ace (HR2-429) contains three aliquots of 6 unique proteases (a-Chymotrypsin, Trypsin, Elastase, Papain, Subtilisin and Endoproteinase Glu-C) and six aliquots of Proti-Ace Dilution Buffer. Each protease is supplied in a stable, lyophilized format in an optimized digest buffer. Simply add water when ready to use.

Proti-Ace 2 (HR2-432) contains three aliquots of 6 unique proteases (Proteinase K, Clostripain (Endoproteinase-Arg-C), Pepsin, Thermolysin, Bromelain and Actinase E) and six aliquots of Proti-Ace Dilution Buffer. Each protease is supplied in a stable, lyophilized format in an optimized digest buffer. Simply add water when ready to use.

The unique freeze dried formulation of the Proti-Ace kits offers a much improved protease stability compared to liquid protease formulations.
