Crystal grow | Temperature: 298 K / Method: vapor diffusion, hanging drop / pH: 7.4 Details: MICROCRYSTALS WERE INITIALLY GROWN USING THE HANGING DROP METHOD IN LINBRO CULTURE PLATES. CRYSTALLIZATION RESERVOIRS CONTAIN 1.8 - 2.0 M AMMONIUM SULFATE, 50 MM TRIS HCL, 10 MM CACL2, PH 7. ...Details: MICROCRYSTALS WERE INITIALLY GROWN USING THE HANGING DROP METHOD IN LINBRO CULTURE PLATES. CRYSTALLIZATION RESERVOIRS CONTAIN 1.8 - 2.0 M AMMONIUM SULFATE, 50 MM TRIS HCL, 10 MM CACL2, PH 7.4. SIX UL OF 15 MG/ML BOVINE TRYPSIN IN 20 MM 2-AMINOBENZIMIDAZOLE WAS ADDED TO 6 UL OF RESERVOIR. MACROSEEDING WAS USED TO GROW LARGE CRYSTALS (REF 2). SINGLE CRYSTALS WERE WASHED IN 0.8 M AMMONIUM SULFATE, 50 MM TRIS HCL, 10 MM CACL2, PH 7.4. THE WASHED CRYSTALS WERE PLACED IN A 18 HOUR OLD HANGING., VAPOR DIFFUSION, HANGING DROP, temperature 298K | ||||||||||||||||||||||||||||||||||||
