1 | VAPOR DIFFUSION, HANGING DROP | 7.5 | 291.15 | Starting concentration of HRAS A59T GppNHp was 18.1mg/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 0.001mL mother liquor to 0.001mL protein. Mother liquor contained 2.6mM NaCl, 1mM MgCl2, 15.7mM HEPES (pH7.5), 2.5mM DTT, 9.95mM Ca(OAc)2, and 19.9% PEG 3350. |
