X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	?	291	0.1 M HEPES pH 7.0, 0-0.1 M KCl, and 8-14 percent (w/v) PEG 8000. The crystal used in this study grew in the presence of an 11-nt ssDNA containing a 5-CTT-3 PAM and nine nucleotides complementary to the crRNA-guide sequence in a 2:1 oligonucleotide:protein ratio. However, the target DNA is not observed in the electron
