Flux measurements of cations using radioactive tracers
1Department of Biological Sciences, University of Toronto, Toronto, ON, Canada.
Abstract:
Standard procedures for the tracing of ion fluxes into roots of plants are described here, with emphasis on cations, especially potassium (K(+)). We focus in particular on the measurement of unidirectional influx by use of radiotracers and provide a brief introduction to compartmental analysis by tracer efflux (CATE).
