Membrane Partitioning of the Rose-Type Chamber for the Study of Metabolic Interaction Between Different Cultures

Abstract
The Rose tissue culture chamber has been divided into 2 compartments by using half-thickness gaskets with an interposed Nuclepore (General Electric Co.) filter. This permits study of the interaction of 2 different cell populations on each side of the membrane. Radioiodinated serum albumin concentration studies demonstrate rapid distribution of labelled protein across the membrane while its pore size of 0.5 μ or 0.8 μ prevents migration of the cells themselves. Equilibrium between plain medium and radioactive medium was established in 7–9 hr.
