1 | VAPOR DIFFUSION, HANGING DROP | 7.5 | 291.15 | Starting concentration of HRAS A59T GppNHp was 12.1mg/mL in buffer containing 20mM HEPES, 50mM NaCl, 20mM MgCl2 and 1mM DTT at pH 7.5. Used a 24-well plate sealed with Vaseline and total well volumes of 0.402mL. Hanging drops were 0.002mL mother liquor to 0.002mL protein. Mother liquor contained 2.6mM NaCl, 1mM MgCl2, 15.7mM HEPES (pH7.5), 2.5mM DTT, 37.3mM Ca(OAc)2, and 20.5% PEG 3350 |
