The pharmacological relevance of vital staining with neutral red

Experientia. 1979 Nov 15;35(11):1475-6. doi: 10.1007/BF01962793.

Abstract

The uptake of neutral red into the renin-containing juxtaglomerular granules does not inhibit the release of renin either in basal or in stimulated states of renin secretion. The vasodilating effect of neutral red may be due to a nonspecific binding to noradrenaline-receptors in the vascular smooth muscle cells.
