description | ABSTRACT<br /> The research was concerned with isolation of alkaline phosphatase (ALP) from the aqueous extract of Aloe Vera using gel filtration technique.<br /> It was shown that, using gel filtration chromatography on Sephadex G-100, the solution of the proteinous precipitate produced by ammonium sulphate saturation, contained two proteinous peaks. The two peaks possessed a variable activity of alkaline phosphatase, where maximum specific activity was obtained in the first peak with higher molecular weight which showed (28) folds of purification.<br /> Furthermore, the comparative molecular weight of the partially purified alkaline phosphatase (first proteinous peak) using gel filtration was found to be (147353) Dalton. <br /> The research was also concerned with finding the optimum conditions of alkaline phosphatase. Maximum activity was obtained using sodium carbonate- bicarbonate buffer (100 mM) at pH ( 9.7 ), (50ºC) and (30 mM) of di-sodium phenyl phosphate as a substrate.<br /> Using linweaver-Burk plot, it was found that the Vmax and Km have the values of (185.18 enzyme unit/dl of proteinous solution) and (3.9mM) respectively.<br /> The results also predicted that the activity of alkaline phosphatase decreased gradually and reached 76% and 50% from the original value when stored at 4ºC and at room temperature (33-40ºC) respectively for 30 days. |
