Method	pH	Temprature	Details
X-RAY DIFFRACTION	?	293	5 mg/ml polymerase with 5.1 mg/ml (19.5 microM) with 1.14 x molar excess of each RNA (v5' 1-16, v3' 1-18+3 and 15-mer capped primer, see Figure 1a) mixed in 1:1 ratio of 100 mM amino acids, 100 mM Tris/Bicine pH8.5, 8% ethylene glycol (v/v), 4% PEG 8000 (w/v) by hanging drop at room temperature. Soaking was performed with 5 mM GTP, 5 mM CTP and 5 mM MgCl2 for 5h.
