Buffer Composition (prepared in D2O instead of H2O):16% PEG 6000,1 M LiCl,0.1 M sodium acetate, pD 5
Initial Sitting Drop Setup:
Mixed 20 uL of a protein solution containing:
9.6 mg/mL perdeuterated LecA, 5 mM Gal-d10, 5 uM calcium chloride (CaCl2),all dissolved in D2O.
With 20 uL of the well solution.
Crystal Growth & Feeding Process:
Crystals initially appeared after 1 week.
To promote further growth, the crystal was fed three times, each time with 5 uL of a pre-equilibrated drop prepared under the same conditions.
Each feeding occurred one week apart, starting one week after initial crystal formation.
This feeding strategy increased the crystal volume from 0.08 mm3 to 0.74 mm3. |
