Abstract

The distribution of 137Cs+, in the presence of valinomycin, has been used to measure the magnitude of the membrane potential (delta psi) in bloodstream forms of Trypanosoma brucei brucei. Values of the delta psi falling in the range -100 mV to -160 mV were observed and the maintenance of this delta psi was sensitive to certain ionophores and protonophores.

摘要

在缬氨霉素存在的情况下，利用¹³⁷Cs⁺的分布来测量布氏布氏锥虫血流形式中的膜电位（δψ）大小。观察到δψ值在-100 mV至-160 mV范围内，并且这种δψ的维持对某些离子载体和质子载体敏感。
