The use of mammalian cortical kidney slices for the study of tubule secretion: a pioneering step toward understanding organic anion transport.

The article examines R.J. Cross and J.V. Taggart's paper "Renal tubular transport: accumulation of p-aminohippurate by rabbit kidney slices." In the paper, Cross and Taggart examined the factors that influence the renal tubular transport of para-aminohippurate (PAH). The study showed that the transport of PAH into the cells was against an electrochemical gradient and required energy.
