Abstract

The specific electrical conductivity and dielectric permeability of aqueous solutions of human blood serum albumin in the 1--15 MHz range have been measured. No conductivity changes within these frequencies conspicuous of the relaxation processes have been noted. The decrease of solution dielectrical permeability with the growth of albumin concentration and the excess of its values for denaturated albumin in comparison with native one makes it possible to assume that the anomaly low-frequency dispersion zone has been passed by the beginning of the measured range (1 MHz).

摘要

已测量了人血清白蛋白水溶液在1-15MHz范围内的比电导率和介电常数。在这些频率范围内未观察到明显的弛豫过程导致的电导率变化。随着白蛋白浓度的增加,溶液介电常数降低,并且与天然白蛋白相比,变性白蛋白的值过高,这使得可以假设在测量范围(1MHz)开始时已经越过了异常低频色散区。
