## Abstract Cells immobilized in gels experience potential metabolic restrictions in the form of reduced diffusion rates of metabolites and ions and their possible selective adsorption on the gel matrix. Diffusion and relaxation characteristics of common solutes in agarose and barium alginate gels
n order to get a better insight into the layer of 'kxtdeosed" counterions, 23Na relaxation measurements have been carried out upon progress&e addition of ClNa to a solution of the tetramethyf ammonium salt of pol~a~~lk acid-The!-' show that for r = Na\*/TMA\* < 1, the relaxation rate is a fast decre
Reduction of the salt concentration of small volumes (0.1 ml or less) of solutions of macromolecules can be accomplished by placing the solution in a small well in an agarose gel. This technique has been especially useful in preparation of samples for electron microscopy.
