| 1 | VAPOR DIFFUSION, HANGING DROP | 5.2 | CRYSTALS OF PEL10ACM WERE GROWN BY VAPOUR-PHASEDIFFUSION USING THE HANGING-DROP METHOD WITH SCREENING AS DESCRIBED BY BRZOZOWSKI & WALTON (2001 [[BRZOZOWSKI, A.M. & WALTON, J.(2001). J. APPL. CRYST. 34, 97-101.]] ). THE PROTEIN CONCENTRATION WAS 30 MG ML-1 IN NA MES BUFFER PH 5.2 CONTAINING KSCN AT A CONCENTRATION OF 200 MM. THE PRECIPITANT WAS 20%(W/V) MONOMETHYL POLYETHYLENEGLYCOL 2000. THESE CONDITIONS FOR THE NATIVE P21 CRYSTALS WERE MODIFIED BY ADDING 25MM CACL2, WHICH RESULTED IN CRYSTALS BELONGING TO SPACE GROUP P21212 | |
