Comparison of purification yield and protein recovery of three Nickel-magnetic matrices for His-ProT and His-Mre11 recombinant proteins. Purification yield was defined as the sum of the percents of the specific band densities at four elution steps (E1-4). Recovery percent was calculated as the percent of purification yield divided by specific binding capacity. SiMAC-Nickel (A), SiMAG/N-NTA/Nickel (B) and SiMAG/CS-NTA/Nickel (C).
