Frozen ...Details: Commercial screen Index 44 (0.1 M HEPES pH 7.5, 25% w/v PEG3350) was chosen for SARS-CoV-2 nsp1 (residues 10 to 126) crystallisation in large quantities using hanging drop method. Frozen stocks of SARS-CoV-2 nsp1 (residues 10 to 126) were thawed on ice and centrifuged in a Thermo Scientific Pico 17 Microcentrifuge, 24-Pl Rotor at 4 degrees, 20000 rpm for 10 min to remove aggregates before the determination of the protein concentration. Subsequently, the protein stock was diluted to 20 mg/mL with precrystallisation buffer (10 mM HEPES and 300 mM NaCl). 400 uL of Index condition 44 was added into each reservoir well. Five protein drops were set on each cover slip by mixing 1 uL of protein solution with 1 uL of the reservoir. The 24-well Linbro plates were incubated at 18 degrees. |
