Instead of eluting our samples under denaturing conditions, we elute triple hemagglutinin (3×HA)-tagged bait/prey complexes in their native form with a competitive peptide simulating the 3×HA tag of the bait protein. Matrix-unspecific interacting proteins and Co-IP antibodies remain on the matrix instead of being eluted under conventionally applied denaturing conditions. We optimized the elution by altering incubation time, eluent concentration, and temperature. These improvements result in more pure proteins. This strategy not only
