Luminal [NaCl] dependency of MD PGE2 release in cell preparations from rabbits fed a low-salt diet. (a) Representative recording shows step-by-step increases in HEK/EP1 cell fura-2 ratio in response to graduated reductions in luminal [NaCl] from 80 to 0 mM. (b) Relationship between biosensor cell responses and luminal [NaCl]. Data points represent mean ± SE, n = 4, all low-salt preparations.
