詳細

詳細

Bromocresol Purple, also known as dibromo-o-cresolsulfonphthalein, is an acidic dye and belongs to the phthalein and sulphonphthalein dyes group. The dye color changes from yellow to violet at pH 5.2-6.8. The monosodium salt of the dye is 8% soluble in water and 2% in ethanol. Bromocresol Purple, under alkaline conditions, forms a hydrophilic, moderately sized dianion that is purple.

アプリケーション

Bromocresol Purple is widely used as a vital stain to trace fluid diffusion in the lymphatic system. In addition, the dye is suitable to differentiate dead or live yeast cells. As a pH indicator, Bromocresol Purple is used in microbial culture media, both broth, and agar. In analytical experiments, e.g., to stain carbonic anhydrase isoenzyme on cellulose acetate electrophoresis membranes, bromocresol purple is used.
