Nigericin 44-53 LOW QUALITY PROTEIN: renin Oryctolagus cuniculus 101-106 1590424-2 1992 Renin secretion was stimulated by adding the K(+)-H+ exchange ionophore nigericin or a weak base, benzylamine, to Ca(2+)-free incubation medium. Nigericin 72-81 LOW QUALITY PROTEIN: renin Oryctolagus cuniculus 0-5 1590424-7 1992 However, when renin secretion was first stimulated by nigericin or benzylamine in Ca(2+)-free medium, subsequent addition of Ca2+ to the incubation medium failed to reverse the stimulation. Nigericin 54-63 LOW QUALITY PROTEIN: renin Oryctolagus cuniculus 14-19
