Here, native SAD procedures are described to enhance signal to noise in anomalous diffraction by using multiple crystals in combination with synchrotron X-rays at 6 keV. Increased anomalous signals were obtained at 6 keV compared with 7 keV X-ray energy, which was used for previous native SAD analyses. A feasibility test of multi-crystal-based native SAD phasing was performed at 3.2 A resolution for a known tyrosine protein kinase domain, and real-life applications were made to two novel membrane proteins at about 3.0 A resolution. The three applications collectively serve to validate the robust feasibility of native SAD phasing at lower energy.
