| 1 | VAPOR DIFFUSION, HANGING DROP | 4.6 | 286 | CRYSTALS WERE OBTAINED AT 13 DEGRESS C IN 1-5 DAYS FROM HANGING DROPS CONTAINING 1.2 MICROLITERS OF PROTEIN: COMPOUND SOLUTION (1:5 MOLAR RATIO) AND 1.2 MICROLITERS OF PRECIPITATING SOLUTION (0.05 M CITRATE-PHOSPHATE, PH 4.6, 0-25 MM NACL, 21 % (W/V) PEG-3350). TO OBTAIN LARGER CRYSTALS, STREAK SEEDING WAS EMPLOYED USING THE CRYSTALS JUST MENTIONED AS DONORS, UNDER THE SAME CONDITIONS EXCEPT 275 MM NACL WAS USED AND THE DROPS WERE EQUILIBRATED OVERNIGHT BEFORE SEEDING WAS PERFORMED |
