PROTEIN-INCORPORATED SERUM TOTAL ANTIOXIDANT CAPACITY MEASUREMENT BY A MODIFIED CUPRAC (CUPRIC REDUCING ANTIOXIDANT CAPACITY) METHOD

, 2012
Due to inadequacies in analytical methodology of total antioxidant capacity (TAC) measurement, proteins are initially separated from the human serum matrix by precipitation and are left unmeasured, thereby causing an important "antioxidant gap.'' The aim
