Purification and Characterization of Alkaline-Thermostable Protease Enzyme from Pitaya (<i>Hylocereus polyrhizus</i>) Waste: A Potential Low Cost of the Enzyme

<table>Cation exchange and gel filtration chromatography plots. (a) shows the cation exchange chromatography on SP-Sepharose (when the column was equilibrated with Tris-HCL at pH 8.0). The protein of interest eluted in the unbound samples. (b) The nonretained fraction from SP-Sepharose 200 was loaded to gel filtration chromatography on Sephacryl S-200. Column was eluted with linear salt gradient in the same buffer.</table>
