1 | VAPOR DIFFUSION, HANGING DROP | 6.2 | 277 | Protein was preincubated with the JIP1 peptide at a 5x molar excess. Protein concentration 9-12.6 mg/mL. Hanging drops consisted of 2uL protein plus 2uL well solution over 1 mL of well solution. Well solution: 2.8-3.1 M Ammonium Sulfate, 10-14% glycerol. For Co-crystallization experiment compound was dissolved in DMSO at 100 mM concentration. Allow to incubate for at least an hour on ice. Solution was spun for 5 minutes at 2000g prior to setting up for crystallization. , pH 6.2, VAPOR DIFFUSION, HANGING DROP, temperature 277.0K |
