Data validation

There are no models related to this curve.

Synchrotron SAXS data from solutions of nanobody2 in complex with the extracellular domain of human BCMA in 20 mM Tris, 100 mM NaCl, pH 8 were collected on the BL19U2 beam line at the Shanghai Synchrotron Radiation Facility (SSRF; Shanghai, China) using a Pilatus 1M detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.103 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.60 mg/ml was measured at 25°C. 20 successive 1 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.
