[Ionic conductance of protein films at the temperatures -50-0 C]

Based on the analysis of the dielectric Maxwell's relaxation in a double-layer construction of protein and lavsan films an electrodeless method for measuring a. c. conductivity of protein films was developed. The conductivity of BSA films soaked in electrolyte solution was shown to retain its ionic character at subzero temperatures up to -50 degrees C in spite of an about 3-orders drop in the conductivity at 0 degrees C.
