Micro diffusion cells for the growth of single protein crystals by means of equilibrium dialysis

Microdiffusion cells are described for crystallization of small volumes of protein solutions by equilibrium dialysis against a precipitant. The cells which may contain down to 10 microliters of protein solution are made either from capillaries of glass or transparent polymer sealed with cellophane membranes or from X-ray capillaries sealed with semipermeable diaphragms of polyacrylamide. The use of these microdiffusion cells has been explored...
