| 1 | VAPOR DIFFUSION | 6.5 | 287 | 8mg/ml protein in 20mM Hepes (pH7.5), 100mM NaCl, 5% w/v glycerol, 1mM EDTA, and 1mM DTT. Equal volume of protein and precipitant (20mM MES (pH 6.5), 12% w/v PEG20K) were equilibrated by vapor diffusion at 14C. Cryosolution is precipitant plus 5% more PEG20K and 20% w/v glycerol., VAPOR DIFFUSION, temperature 287K |
