The uptake of proteins into the coacervates is charge‐driven. A) The net charges on three GFP mutants dictate their uptake into coacervates formed from 2:1 Q‐Am/CM‐Am (DS Q=DS CM=0.8). The contrast for GFP(−8) has been increased to compensate for very low fluorescence from the polymer‐poor phase. B) The uptake of negatively charged GFP(−30) is dependent on the ratio of Q‐Am to CM‐Am. The normalized GFP fluorescence of the coacervate phase is indicated for each set of conditions. Scale bar: 5 μm.
