X-RAY DIFFRACTION 8 291.15 Crystals of AblFL in complex with SKI and asciminib were obtained by combining 0.3 ul of 600 uM AblFL + 700 uM SKI + 700 uM asciminib (~32 mg/ml) in 5 percent DMSO with 0.4 ul reservoir of 0.1 M Tris-HCl pH 8 + 1.75 M Ammonium sulfate + 2 percent (v/v) polypropylene glycol 400 (PPG 400). The final stock of complex was concentrated from 1 uM AblFL with ~1.2 uM SKI/asciminib after incubation at 4 degree C for 6 h. Screening around this condition yielded crystals in a transparent diamond-shaped or plate-shaped crystals. Crystals were grown at 18 degree C by sitting drop for a few days. The crystals were transferred to a drop of fresh reservoir containing 20 percent Xylitol with matching concentration of inhibitors in 5 percent DMSO for few seconds for cryo-protection
