ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	9	277	5-MUT TT-LDH WAS CRYSTALLIZED AT 10MG/ML BY THE HANGING-DROP VAPOUR-DIFFUSION METHOD, FOLLOWING THE MIXING OF THE PROTEIN AND THE MOTHER-LIQUOR SOLUTIONS AT A 1:1 RATIO. THE MOTHER LIQUOR SOLUTION WAS 0.1 M HEPES BUFFER PH 9, 18-20% PEG 6000, 2 M LICL2, 500 MICROMOLAR ADP. CRYSTALS GREW WITHIN A WEEK AT 4 DEGREES CELSIUS.
