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 Resolution 2.86 Å R-free 0.348
