ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	7.5	277	5 mM Ile-AMS and 16.5 mg/ml mut-GVHH-PmIleRS2 were mixed in 1:1 ratio with the well solution containing: 0.2-0.5 M Potassium tartrate, 10-20 % (w/v) PEG3350, 25 mM Hepes-KOH pH=7,5 at 20 oC, 50 mM NaCl. The drop volume of 2 microliters, was equilibrated towards 300 microliters of the well solution at 4 degrees.
