ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5		4 UL HANGING DROPS (2 UL OF DAPDC 10 MG/ML CONTAINING 5MM OF LYSINE COMBINED WITH 2 UL OF WELL SOLUTION) WERE EQUILIBRATED AGAINST 500 UL OF WELL SOLUTION (24% PEG-MME 5K, 0.1M MES BUFFER PH6.3 AND 60 MM AMMONIUM SULFATE). THESE CRYSTALS WERE SOAKED FOR 3 HRS IN IN MOTHER LIQUOR CONTAINING 0.2 MM PLP. THE CRYSTALS ARE DISTINCTLY YELLOW., pH 6.50
