1 | VAPOR DIFFUSION, HANGING DROP | 7 | 298 | Crystallization drops were prepared by mixing 2 uL of stock peptide solution with 2 uL of mother liquor and allowed to equilibrate at 298 K over a well containing 500 uL of mother liquor. The stock peptide solution (total concentration 1.5 mM) was prepared by mixing 2:1 ratios of the A16 peptide with me-F16 in 10 mM potassium phosphate, 100 mM potassium chloride pH 7.0. |
