Guanidine thiocyanate is a potent protein denaturant (stronger than guanidine HCl) often used in the isolation of intact ribonucleic acid to eliminate RNase activity. RNase can recover activity after boiling, but is irreversibly inactivated in a 4 M solution of guanidine thiocyanate. Such solutions,...
The yellow stuff is a copper (I) compound. When some concentrated HCl is added to the yellow stuff, then a dark solution is obtained, which becomes bright green on addition of some H2O2. The H2O2 oxidizes all copper (I) to copper (II), which in turn forms a green complex with ...
0.5 M HCl in the absence and presence of different concentrations of DDTC at 30 were shown in Fig. 2. As it can be seen that, the corrosion potentials obviously shifts to more negative direction while the cathodic curves are shifted to lower current density region compared to that[translate]...
