X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.	?	HPLC PURIFIED SI-CRAMBIN PROTEIN WAS DISSOLVED AT 25 MG/ML IN 80% ETHANOL/WATER (V/V), AND EQUILIBRATED AGAINS 60% ETHANOL. AFTER 10 DAYS, THE RESERVOIR WAS LOWERED TO 50% AND MICROSEEDED BY THE STREAK SEEDING METHOD (CAT WHISKER). AFTER LOWERING THE RESERVOIR TO 45%, GOOD CRYSTALS WERE FORMED., pH 7., vapor diffusion - hanging drop - microseeding
