(A) Presentations of the scattering at the solvent conditions indicated. Lines show MFF fit. (B) Rg for PNt in water and 4 M Gdn are consistent with values for chemically denatured proteins (1). Other polymer limits are shown for comparison. Most errors are smaller than data points. (C) Dependence of Rg (left) and ν (right) on Gdn [solid points are colored according to (A); open points are replicates; error bars shown are fitted error].
