CI2 stability in p -NIPAm- co -AAc: Results are shown for dilute solution (blue) and 10 g/L p-NIPAm-co-AAc (green). Error bars reflect the standard error in k
values from three trials. Colored arrows indicate the average ΔG0*
values for globally exchanging residues  in crowded (5.2 kcal/mol) and dilute (4.9 kcal/mol) solution.
