Table 1. Curve fits for titrations of Cp183 capsid by SRPKΔ.

	A	B	C	D	Average
N	51.17	45.35	47.97	52.84	49±3
K D (nM)	32.03	32.39	27.68	33.40	31±3
K D'(nM)	1.21	0.40	0.54	0.25	0.6±0.4
C' (nM)	25.09	7.78	18.54	5.71

There were 4 trials of titration: A, B, C and D. In trials B and D, the free dimer concentration (C') was depleted by size exclusion chromatography prior to the titration.
