Figure 2From: Profiling and quantitative evaluation of three Nickel-Coated magnetic matrices for purification of recombinant proteins: helpful hints for the optimized nanomagnetisable matrix preparationSDS-PAGE analysis of flowthrough fractions of His-recombinant proteins bound onto the different concentrations of three Nickel-coated magnetic matrices. His-ProT and His-Mre11 recombinant proteins in soluble cell extract (SCE) of E.coli were bound to increasing concentrations of magnetic matrices, SiMAC-Nickel, SiMAG/N-NTA/Nickel and SiMAG/CS-NTA/Nickel, and flowthrough fraction of each matrix at each concentration was subjected to SDS-PAGE analysis. The target proteins are shown by black arrows.Back to article page
