Abstract: | A dye mixture, consisting of a celestine blue B dispersion (prepared according to Gray et al. 1956), orange G, and acid fuchsin in one solution, simultaneously stains nuclear elements and gives double contrast staining of cytoplasmic elements. Orange G, 0.16 gm, and acid fuchsin, 0.04 gm, dissolved in 100 ml of celestine blue B dispersion and adjusted to pH 0.8 gives, when applied for 1.5 min, results comparable or superior to other “triple contrast” stains on a wide variety of tissues. No differentiation other than that which occurs during dehydration is necessary. |
