1VAPOR DIFFUSION, SITTING DROP7293Performed using the sitting drop vapour diffusion method, by adding 1ul (4mM) L-[Ru(phen)2(dppz)]2+ to a drop containing 1ul (1mM) d(TCGGTACCGA)2, and 8ul of a solution containing 12mM spermine, 10% 2-methyl-2,4-pentanediol, 40 mM sodium cacodylate pH 7.0, 80 mM NaCl and 20 mM BaCl2. This was equilibrated against 1 ml of 35% 2-methyl-2,4-pantanediol at room temperature, 20 C., VAPOR DIFFUSION, SITTING DROP, temperature 293K
