Abstract
A simple chemotactic apparatus and method wherein surface tension is used to hold cell suspensions, chemotactic factors, and control fluids in place on membrane filters. In some embodiments, chemotaxis factors and controls are placed on one side of a membrane filter, and cell suspensions are placed on the other. Gravitational flow is limited by the effect of surface tension on the fluids. In some of the preferred embodiments, grids, sheets, or occluding materials are used to further limit the gravitational fluid flow.
