It has been found by the conductometric impulse method that membrane conductivity of human erythrocytes rises about 70 times at heparin concentration in blood samples above 0.2 mg/ml. The presence of edetic acid (EDTA) in blood samples inhibits the rise of membrane conductivity on addition of heparin.

Interaction of DNA with planar bilayer phosphatidylcholine membrane in the presence of CaCl2 increases electric conductance of the membrane several times as a result of the formation of DNA-membrane complex. The same effect was observed in the cases of ribosomal RNA and synthetic homopolymers polyA, polyU and polyA X polyU double helix.
It was shown that a change in conductance and capacitance of BLM can be explained by Ca++ BLM--heparin complex organization.
