Levels of enzymatic activities involved in antioxidant defense.

Enzyme Activity	Specific Activity (mU/mg)
Enzyme Activity	ADF	HLEC	BLEC
Glutathione reductase	50.7 ± 1.2 ⁽****⁾ ^(####)	13.7 ± 2.3	14.0 ± 0.98
Glutathione peroxidase	1.4 ± 0.4	1.77 ± 0.16	1.6 ± 0.58
Catalase	5800 ± 238 ⁽****⁾^{, (####)}	1390 ± 142	348 ± 53.1
Glutathione S-transferase	580.0 ± 54.2 ⁽****⁾^{, (####)}	34.7 ± 2.3	24 ± 5.4

The values are the mean ± SEM from at least three independent biological repeats. See Section 2.5 for details on the assays. Statistical significance of ADF with respect to HLEC (*) and of ADF with respect to bovine lens epithelial cells (BLEC) (#); **** and ^#### p < 0.0001.
