## A ,Convenient Technique for Dialysis ' Variations in the hydrolysis procedure may atlect the yield of individual steroids; see, for example, the enzymic procedure of Givner et al. ( 1) for estrogen determinations. The hydrolysis problem is under investigation by Dr. B.
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.
A simple equilibrium dialysis cell may be quickly prepared from common, inexpensive microcentrifuge tubes. The resulting cell is easy to use and precise enough for quantitative dialysis studies of small samples (<SO ~1). In addition, by using a portion of the cell, exchange dialysis of small samples
