1	MICROBATCH	8.5	293	Crystals were grown by seeded micro batch in a glass depression plate, on glass coverslips. The experiment was sealed with FOMBLIN oil. 2 microliters of protein saturated with geranylgeraniol was mixed with 1 microliter of seed stock and two microliters of reservoir solution. The reservoir solution was composed of 1.2 molar ammonium sulfate and 0.1 molar TrisHCl buffer at pH 8.5. The reservoir was saturated with geranylgeraniol by adding several microliters of neat geranylgeraniol.
