Effects of Reduced Glutathione, Surface Active Agents, and Ionic Strength on the Detection of Metallothioneins by Using of Brdicka Reaction

Original language description

We investigated the effects of two surface active agents (sodium dodecyl sulfate, SDS, and polyoxyethylene sorbitol, Tween-20), ionic strength and reduced glutathione (GSH) on MT signals measured by adsorptive transfer stripping differential pulse voltammetry Brdicka reaction. If we compared the GSH and MT signals at the accumulation time of 120 s, the MT signal was more than two hundred times higher than the GSH one. The influence of Tween-20 was investigated in a broad concentration range (from 10(-8)to 10(-11) %, v/v). We found that the catalytic Cat2 signal decreased for more than 60% with increasing Tween-20 content. In the case of using SDS (10(-3) - 10(-6) M), the increase of Cat2 peak in the presence of the highest SDS concentration was determined. The height of Cat2 peak enhanced with increasing ionic strength mimicking by NaCl concentration. Based on the enhancement of the Cat2 peak we determined the ionic strength of fibroblasts sample and recalculated the concentration of
