Crystalization Experiments
Method Microdialysis
pH 7.5
Details CRYSTALS WERE PREPARED AT PH 7.5 BY MICRODIALYSIS METHOD WITH AMMONIUM SULFATE AS THE PRECIPITATING AGENT. THE INNER SOLUTION 100 MICROLITER CONTAINED 1.5 % (W/V) GSHASE, 5 MM MGCL2 AND 10 % SATURATED AMMONIUM SULFATE IN 50 MM TRIS-HCL BUFFER (PH 7.5). THE INNER SOLUTION WAS DIALYZED AGAINST 50 MM TRIS-HCL BUFFER (PH 7.5) WHICH CONTAINED 5 MM MGCL2 AND 25 % SATURATED AMMONIUM SULFATE.TRIS-HCL BUFFER, microdialysis
