data from solutions of
Human wild-type telomere 72mer d(TTAGGG)12
6 mM Na2HPO4, 2 mM NaH2PO4, 1 mM Na2EDTA, 185 mM KCl, pH 7.2
BioCAT 18ID beam line
at the Advanced Photon Source (APS), Argonne National Laboratory storage ring
(Lemont, IL, USA)
using a Pilatus3 X 1M detector
at a sample-detector distance of 3.5 m and
at a wavelength of λ = 0.1033 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 250.00 μl sample
at 10 mg/ml was injected at a 0.75 ml/min flow rate
onto a GE Superdex 75 Increase 10/300 column
0.500 second frames were collected.
The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
