1	VAPOR DIFFUSION, SITTING DROP		293	NaK2K protein was mixed with 50mM MES pH 6.5/100mM potassium citrate/200mM TlNO3/56%-68% MPD while 50mM MES pH 6.5/100mM potassium citrate/200mM KNO3/56%-68% MPD was used for the reservoir. Crystal is transferred to 100mM TlNO3/50mM MES (pH 6.0 or 6.5)/100mM sodium citrate/56%-68% MPD
