86Rb is not a reliable tracer for potassium in skeletal muscle

For technical reasons, 86Rb is frequently preferred to 42K as a tracer for K+. Systematic comparisons of the two isotopes, however, are rarely done. In this paper we compare the transport of 42K and 86Rb in rat and mouse soleus muscle and in rat erythrocytes. Ouabain-suppressible K+ uptake in rat so...
