WebMast cell granules will stain a reddish-purple with toluidine blue. Metachromasia is pH dependent. Many substances are only metachromatic when stained as frozen sections. Usually they must be viewed immediately, if not sooner. Metachromasia (var. metachromasy) is a characteristical change in the color of staining carried out in biological tissues, exhibited by certain dyes when they bind to particular substances present in these tissues, called chromotropes. For example, toluidine blue becomes dark blue (with a colour range from blue-red dependent on glycosaminoglycan content) when bound to cartilage.
