“…5 is 60 mV/pH, which is reasonable for the protonation of these kinds of molecules. For the pK-values one obtains 2.85 for the second protonation of the diamonium cation and 3.25 for the first protonation of the diimonium cation, which are of the same order as those given in the literature [13]. According to U' vs. pH the pK-value of the semioxidized species will fall somewhere between these two values.…”

“…In the other experiments the photo-oxidation of dimethyl-p-phenylene-diamine by fluorescein triplets was investigated using a photoflash technique. Since, in this case, equal amounts of semireduced fluorescein and semioxidized dimethyl-p-phenylene-diamine should be formed by charge transfer and since the extinction coefficient of the semireduced fluorescein is known [13] the &-value of our semioxidized species can be easily determined. In this experiment any subsequent reactions can be ignored in the determination of c. With both methods we obtained E = (1.0 f 0.05) lo4 I mol-' cm-' at From the measurements of E by the first method there were some indications that E decreases somewhat at higher concentrations.…”

“…Because of the toxicity associated with protein aggregation, living systems have evolved complex quality control mechanisms, collectively known as protein homeostasis system, that reduce the presence of protein aggregates 6,7 . These mechanisms enable the regulation of protein synthesis, trafficking, interactions and degradation, and involve a wide range of cellular components, including enzymes 8 , molecular chaperones 6 , metabolites 9 and lipids 10 , which we are only beginning to understand in detail.…”

“…Since the decay of the photocurrent is rather slow in the latter case, it should be possible to detect the intermediate species. According to photochemical data, the anion radical of fluorescein should absorb around 390nm [7][8]. In order to detect the radical, we performed absorption and photocurrent measurements simultaneously, using a cell with transparent Sn0,-electrodes.…”
