Drops were equal volumes of a 6 mg/ml STMV stock solution buffered at pH 6.5 with 0.1 M phosphate. The reservoirs were 16% saturated ammonium sulfate in 0.1 M phosphate at pH 6.5. Drops were 6 to 8 ul with 0.60 ml reservoirs. Crystals were grown at 4 degrees C over a weeks time. PH range: 4.5 - 7.0 |
