coli BL21(DE3) containing plasmid pANT43 was inoculated from an overnight preculture at a 1:100 ratio in four 2 l baffled Erlenmeyer flasks filled with 400 ml TB medium containing 50 g ml 1 kanamycin sulfate and incubated at 37 C, 140 rpm using a 5 cm shaking diameter for 2.75 h
The endogenous lens hromofore, tryptophan metabolites (kynurenine, 3-hydroxykynurenine, 3-hydroxykynurenine glucoside), which are relatively inert photochemically, during oxidative stress and/or aging are formed photochemically active tryptophan metabolite (N-formyl-kynurenine, xanthurenic acid) that have photochemical properties, and also act as an endogenous photosensitizers in the lens 53
