Figure 6. Electrophoresis in 10% PAAG of proteins of E. coli cells expressing the renalase gene: 1 - total protein of cells without induction; 2 - total protein of cells after IPTG induction; 3 - renalase protein with a molecular mass of 39 kDa (Ren 39 kDa) after purification on a with Ni-Sepharose column; M - protein molecular weight marker (19 kDa, 25 kDa, 34 kDa, 49 kDa, 85 kDa and 117 kDa).
