The lyophilisate was disolved in water so that the HLE concentration was 5 mg/ml (170 micromolar) and the acetate concentration 250 millimolar. 120 microliter dissolved HNE lysophilisate was mixed with 6 microliter inhibitor solution (10 mM in DMSO). 1 microliter of the resulting HLE/inhibitor mixture was mixed with 0.5 microliter reservoir solution which was composed of 20 % PEG MME 5000, 0.2 M potassium sulphate. Repeated seeding was necessary to get usable crystals. In the final seeding step the reservoir was composed of 20 % PEG MME 5000, 0.2 M sodium sulphate. PH range: 5-7 |
