A note on the “split oil drop” technique

  • B. Gunnar Wallin


A modification of the “split oil drop” technique was used for determination of water permeability in crayfish axons. To decide how well the oil drops sealed the lumen of the axon different types of control experiments were parformed. The results suggested that the oil drop diameter was only about 94% of the axon diameter. The possible occurrence of such leaks between oil drops and surrounding membrane wall when using similar methods in other organs is discussed.
