Fitting parameters of the SAXS data recorded under Conditions A–F.

The experimental SAXS patterns are shown in various figures as indicated in the text. Condition A: hemocyanin concentration 5.0 gL, 50 mM Tris/HCl pH 7.0, 100 mM SCN; Condition B: hemocyanin concentration 5.0 gL, 50 mM phosphate pH 7.0, 100 mM SCN; Condition C: 50 mM Tris/HCl pH 7.0; the sample marked with () contains also 40 mM CaCl; Condition D: hemocyanin concentration 5.0 gL, 50 mM glycine pH 9.5, EDTA 5 mM, 100 mM SCN; Condition E: 50 mM phosphate pH 7.0, 5 mM sodium dithionite; Condition F: 50 mM Tris/HCl pH 7.0, 5 mM sodium dithionite. The entries in column “Experiment” identify the experimental runs in Tables S1, S2, S3; [Hc]: hemocyanin concentration in gL; as from Fig. 2a of Ref. [8]; as from Fig. 1 curve b; as from Fig. 2c of Ref. [8].
