1		10.5	292	The core dimer complex was concentrated to an optical density of ~100 at 875 nm and washed in (0.42%) n-nonyl- -D maltopyranoside to exchange the purification detergent, n-dodecyl- -D-maltopyranoside. Crystals grew in 14.00% PEG400, 0.10 M N-cyclohexyl-3-aminopropanesulfonic acid (CAPS) pH 10.5, and 1.0% spermidine., VAPOR DIFFUSION, SITTING DROP, temperature 292K
