1	VAPOR DIFFUSION, SITTING DROP		277	Bat FluA polymerase bound to the ends of the RNA promotor (5 prime end nts 1-16, 3 prime end nts 1-18) was co-crystallized in a 1:8 ratio with the thiophospho-serine-5 22-mer Pol II CTD peptide mimic in 0.8 M sodium-potassium phosphate at pH 5.0. Crystals were set at 4 C using seeding.
