1 | VAPOR DIFFUSION, SITTING DROP | 9 | 298 | SIAH1 AT 17.6 MG/ML WAS MIXED WITH A TWO-FOLD EXCESS OF USP19 PEPTIDE ON ICE FOR 30 MIN. BEFORE SETTING UP FOR CRYSTALLIZATION. CRYSTALS WERE GROWN AT 298K USING THE SITTING DROP METHOD BY MIXING 0.5 UL PROTEIN:PEPTIDE MIX WITH 0.5 UL WELL SOLUTION CONSISTING OF 20% PEG6000, 0.1 M BICINE PH 9.0. THE CRYSTALS WERE CRYOPROTECTED BY FIRST IMMERSION IN WELL SOLUTION MIXED WITH 15% (FINAL) ETHYLENE GLYCOL, THEN IMMERSION IN N-PARATONE. |
