Values are means from four separate tissue biopsy specimens obtained from control subjects. Intensities are shown as weak (+) to strong (+++) as described in the Methods section. The difference between the published molecular weights of Prx III and VI (fig 1 and table 1) is due to post-translational modifications as published earlier.16,20,23,26
