data from solutions of
Full-length polypyrimidine tract binding protein (PTB)
25 mM Tris, 250 mM NaCl, 2 mM DTT, pH 7.2
EMBL X33 beam line
at the DORIS III storage ring
using a 1D Gas detector detector
at a sample-detector distance of 2.4 m and
at a wavelength of λ = 0.15 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
Solute concentrations ranging between 3.4 and 20 mg/ml were measured
60 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.
The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
