Static free-fluid electrophoresis in spaceThe weightless environment onboard spacecraft in drifting flight has provided a unique opportunity to do experiments that cannot be done on the ground. High resolution free-fluid electrophoresis of particles proposed in the late 1960s to take advantage of reduced gravity began with brief experiments done during two Apollo flights. The recent Apollo Soyuz Test Project mission had two major experiments that accomplished the separation of viable biological cells. Experiments now are being planned for the Space Shuttle which will attempt to achieve high resolution of the separated species by using zone electrophoresis. These experiments will return a quantity sufficient for laboratory testing and establish the potential of fractionation and purification of biological materials in space.
