[Studies on the uptake of 8-anilino-1-naphthalene sulfonate by rat freshly isolated renal cells].
The addition of 8-anilino-1-naphthalene sulfonate (ANS) into rat renal cell suspension caused a rapid increase in fluorescence (Ex. 400 nm, Em. 470 nm). The increase in fluorescence seemed to be composed of two phases. When the cells were disrupted by ultrasonic wave, the fast phase (0-ca 20 sec) increased and the slow phase (after ca 40 sec) disappeared. The rate of increase in the slow phase was dependent on the concentration of ANS and on the ambient temperature. A double reciprocal plot of the rate and the concentration exhibited straight line. It was decreased by bromophenol blue and rose bengal but not by other organic anions like p-aminohippuric acid and several metabolic inhibitors. It seemed that the uptake of ANS into the renal cell is mediated by a carrier which is different from that for p-aminohippuric acid.
