Presence of Cu, Zn-SOD within several epidermal areas.

	Breast (n = 3)	Scalp (n = 3)	Ear (n = 3)	Arm (n = 3)	Thigh (n = 3)	Face (n = 5)	Back (n = 4)
Horny	0.25 ± 0.06	0.24 ± 0.039	0.528 ± 0.13	0.17 ± 0.03	0.34 ± 0.034	0.29 ± 0.063	0.26 ± 0.048
Basal	0.22 ± 0.07	0.217 ± 0.056	0.448 ± 0.16	0.166 ± 0.04	0.19 ± 0.062	0.26 ± 0.06	0.21 ± 0.053
Total	0.235 ± 0.06	0.228 ± 0.047	0.488 ± 0.14	0.168 ± 0.035	0.265 ± 0.03	0.275 ± 0.06	0.235 ± 0.05

Mean densitometric values of Cu, Zn-SOD-immunoreactivity in the basal and horny layers of various areas of human epidermis. Generally, the horny layer expresses more Cu, Zn-SOD immunoreactivity than the basal layer. For this experiment random genders were used that confirmed the results illustrated in Figure 1F. The number beside the skin area represents the number of samples analyzed.
