Restriction Grade Factor Xa is a highly purified preparation isolated from bovine plasma and activated with Russell's viper venom. This preparation is purified to near homogeneity and shows no secondary cleavage from contaminating proteases. The preparation is also functionally tested for activity with fusion proteins. Like enterokinase, Factor Xa cleaves at the C-terminal side of the recognition sequence (IleGluGlyArg↓) and can therefore be used for removing all vector-encoded sequences from appropriately designed constructs. Supplied as a solution in 50% glycerol.
