Crystallization

Crystalization Experiments
Method Grown in Gelled Protein Solution with Agarose
pH 4.5
Details HEWL CRYSTALS WERE GROWN IN A GELLED PROTEIN SOLUTION WITH AGAROSE (SIGMA, TYPE VII: OF LOW GELLING TEMPERATURE), 4 % MPD IN ACETATE BUFFER (PH 4.5), THE PRECIPITATING AGENT SOL MPD IN BUFFER. THE GLASS TUBE USED WAS 6 CM TALL WITH AN IN CRYSTALS OF TYPICAL DIMENSIONS $SIM$0.7 $TIMES$ 0.6 $TIM, grown in gelled protein solution with agarose
