In this work, catalytic hydrogen evolution reaction (CHER) of five proteins (human serum albumin, lysozyme, beta-synuclein, H2 A and H3 histones) were studied using constant current chronopotentiometric stripping (CPS) with the aim to find out the association between protein content and its electrochemical response. We have shown that the height and potential of CPS peak H in dependence on accumulation potential differed for the studied proteins, while the CPS peak area was almost the same for all of them. CV and CPS peaks H of Cys-containing proteins appeared at less negative potentials in comparison to proteins without Cys, suggesting easier CHER. Acidic and basic proteins not containing Cys can be also recognized due to their different CPS response after their adsorption at the positive and negative charged interface.
