Experimental results. (a) Section of a 4 × 6 X-CHIP with a two-dimensional optimization of two crystallization conditions for native PA0269 taken two weeks after initial setup. (b) Crystals of EphA3 grown overnight and the crystals were approximately 150 µm in length. (c) On-the-chip diffraction image for an EphA3 crystal collected on a Rigaku FR-E rotating-anode generator using an R-AXIS HTC detector. (d) Part of an experimental electron-density map generated using the SAD PA0269SM data set collected directly from the crystal grown on the X-CHIP superimposed with the protein Cα trace (shown as a solid line). |
