Toluidine blue is a basic thiazine metachromatic dye with high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. It has found wide applications both as vital staining in living tissues and as a special stain owing to its metachromatic property. Toluidine blue has been used in vivo to identify dysplasia and carcinoma of the oral cavity. Use of toluidine blue in tissue sections is done with the aim to highlight components, such as mast cells granules, mucins, and cartilage. This article provides an overview on chemistry, technique, and the various applications of toluidine blue.
甲苯胺蓝是一种碱性噻嗪异染性染料,对酸性组织成分具有高亲和力,因此可对富含DNA和RNA的组织进行染色。由于其异染特性,它在活体组织的活体染色以及特殊染色方面都有广泛应用。甲苯胺蓝已被用于体内识别口腔发育异常和癌。在组织切片中使用甲苯胺蓝的目的是突出显示诸如肥大细胞颗粒、粘蛋白和软骨等成分。本文概述了甲苯胺蓝的化学性质、技术及各种应用。
