Fast preparation of a desiccant array for the gradual desiccation method in protein crystallization screening

The gradual desiccation method (GDM) is a modification of the vapor diffusion method for protein crystallization screening. This method can dramatically increase the chances of obtaining protein crystals and is therefore potentially useful for practical protein crystallization screening. However, it is troublesome to prepare the desiccant for the GDM because each of the 96 desiccants must be of the same mass. Repeated manual weighing of the...
