1	VAPOR DIFFUSION, SITTING DROP	5	281	Bat influenza polymerase protein in 50 mM HEPES-NaOH, 500 mM NaCl, 5 % glycerol, 2 mM TCEP, pH = 7.5 was adjusted to a concentration of 10 mg per ml, mixed in a 1:1 ratio with vRNA, which was an equimolar mixture of nucleotides 1-16 from the 5 prime end and nucleotides 1-18 or 3-18 from the 3 prime end. Protein-RNA was mixed with mother liquor containing 0.7-1.5 M sodium-potassium phosphate at pH 5.0
