Removal from the 5% arginine diet causes a restoration of deoxy-stimulated K⁺ efflux to high values.

The fluxes were measured as described in “Materials and methods” on RBCs from mice on normal chow (Chow) after 10 weeks on the 5% arginine diet (Arg) and after 15 weeks off arginine and on regular chow (Chow). Each point represents the average of one experiment performed in triplicate on one mouse as described in “Materials and methods.” The lines connect the same mouse.
