Small-angle X-ray scattering data of a guanine-rich DNA derived from the promoter region of c-MYC gene in solution

This article presented the small-angle X-ray scattering (SAXS) data of a guanine-rich DNA derived from the promoter region of c-MYC gene (Pu22) in solution. The data is collected under the condition, where the Pu22 takes a guanine quadruplex (GQ) structure. The SAXS curve was also measured and analyzed when 18-crown-6, a chelator of K+ ions, was added to the Pu22 solution.
