  • Method of growing protein crystals
    Patent number: 6579358
    Abstract: A method of growing protein crystals in a protein crystal growth assembly including a crystal growth cell and further including a cell body having a top side and a bottom side and a first aperture defined therethroug, the cell body having opposing first and second sides and a second aperture defined therethrough. A cell barrel is disposed within the cell body, the cell barrel defining a cavity alignable with the first aperture of the cell body, the cell barrel being rotatable within the second aperture. A reservoir is coupled to the bottom side of the cell body and a cap having a top side is disposed on the top side of the cell body. The method includes steps of rotating the cell barrel to orient the insert in a fill/removal position; loading and securing a protein into the insert; rotating the barrel to a launch configuration position; rotating the barrel to activate and experiment by placing the cell in a growth position; and then rotating the barrel further to deactivate the experiment.
