IDMethodpHTemperatureDetails
17.58MG/ML PROTEIN IN 20MM HEPES (PH7.5), 100MM NACL, 5% W/V GLYCEROL, AND 1MM EDTA. EQUAL VOLUME OF PROTEIN AND PRECIPITANT (1.5M AMSO4, 100MM TRIS, PH 8.5 AND 12% W/V GLYCEROL) WERE EQUILIBRATED BY VAPOR DIFFUSION AT 14C. CRYOSOLUTION IS 2.2M AMSO4, 30% W/V SUCROSE, 12% W/V GLYCEROL, AND 100MM TRIS (PH 8.5).
