SUMMARY
The calculated molecular weight of alkaline phosphatase after purification is 100,000 g/mol, significantly higher than the literature value of 89,000 g/mol. The discrepancy may be attributed to the presence of EDTA, which can inhibit the enzyme and potentially increase the measured molecular weight. The discussion highlights the importance of purification methods, such as gel electrophoresis and dialysis, in obtaining accurate molecular weight measurements. Further details on the purification process are necessary to provide a definitive explanation for the observed results.
