Some studies of the diffusion of sodium ions through protein solutions and phospholipid sols

Abstract
Diffusion of sodium-22 in solutions containing sodium chloride, calcium chloride, bovine plasma albumin, lecithin and cholesterol has been examined by two methods which were modifications of the open-end capillary technique of Anderson & Saddington (1949) and the continuous monitoring technique of Mills & Godbole (1958). Preliminary investigations of semi-infinite systems consisting of lecithin sols layered on albumin solutions have been made. The activity in the capillary at various times during diffusion has been compared with the theoretical activity and good agreement has been found.
