Abstract

The protein profile of sera isolated from mice pre-treated with Cu(II) complex of Girard T with superoxide dismutase (SOD)-mimetic activity was analyzed using SDS-PAGE. This complex was intraperitoneally administered (10 mg/Kg body weight) to Swiss albino mice. The resolved polypeptides showed a new sharp band at 100 KDa against which a polyclonal antibody was raised in rabbit. Sera of rabbit anti-100 KDa protein was used as a powerful probe for the detection of 100 KDa protein isolated from sera of treated mice. Western blot assays revealed a strong reactive polypeptide band at 100 KDa in sera of the mice, but no cross reaction was observed with sera of normal mice. The identification of purified polypeptide was confirmed by different characterization experiments.
