“…This sensitive analysis can be carried out in the case of all peptides and proteins, which in their molecule contain cysteine. Among these molecules belongs also MTs [68,72,73,75,82,83,85], glutathione [174,[197][198][199][200][201], phytochelatins [199,200,[202][203][204] and others [205,206], which have been determined by using of stationary electrochemical instrument without autosampler.…”
