					Porod volc	Sequence
D51–335	2.9	2.9	11	65	39	39.0
D5323–785	4.8	4.7	14.5	570	345	53.5 × 6 (321)
D5381–785	2.8	2.8	9	80	48	46.7

^aAbsolute uncertainties for R_g from the Guinier plot, the reciprocal space R_g, and D_max were ±0.05 nm, ±0.1 nm, and ±0.4 nm. The relative uncertainties of the Porod volume and the molecular mass from the Porod volume were 5%.

^bCalculated from the P(r) function.

^cCalculated according to reference 20.
