1 | VAPOR DIFFUSION, HANGING DROP | 291 | 200 microM Dpo4, 240 microM primer-template DNA complex, 5 mM MgCl2, 1 mM dTTP, 20 mM Tris-HCl (pH 7.4), 60 mM NaCl, 2% glycerol (v/v), and 5 mM 2-mercaptoethanol were incubated at 37 C for 5 min. Droplets (a 1:1 mixture of Dpo4-DNA complex mixture and the reservoir solution, v/v) were equilibrated against a reservoir solution containing 0.1M Tris-HCl (pH 7.4), 13% polyethylene glycol 3350 (w/v), 0.1 M Ca(CH3COO)2, and 2% glycerol (v/v). |
