产品介绍

结晶 紫常用于革兰氏染色及其变体、 染色淀粉样物质、细菌成分和维管植物组织。它用于环氧树脂切片的多色染色、 培养神经元的活性染色以及分析减数分裂结构的 共聚焦光学切片。它还被用于细胞内细菌、微孢子虫孢子和细胞学涂片的 吖啶橙-结晶紫染色。应用:

革兰氏结晶紫溶液,也称为龙胆紫或六甲基副玫瑰苯胺,是一种基本、阳离子、嗜酸性氨基芳甲烷染料。它是六-N-甲基化的三氨基三苯甲烷,具有中等大小的亲脂性阳离子和轻微非平面的共轭体系。在细菌学中,它用作革兰氏染色的主要染料,以区分革兰氏阳性菌和革兰氏阴性菌。众所周知,它具有抗菌和抗真菌的特性。

Gram’s crystal violet solution, also known as gentian violet or hexamethyl pararosaniline, is a basic, cationic, acidotropic aminoarylmethane dye. It is a hexa-N-methylated triaminotriphenylmethane with a moderately sized lipophilic cation and a slightly nonplanar conjugated system. It is used in bacteriology as the primary stain in Gram staining to differentiate Gram-positive and Gram-negative bacteria. It is known to possess antibacterial and antifungal properties.
Application:
  • Crystal violet is routinely used for Gram staining and its variants, staining amyloid, bacterial components, and vascular plant tissues.
  • It is used in polychrome staining of epoxy resin sections, viability staining of cultured neurons, and confocal optical sectioning to analyze meiotic structures.
  • It is also employed in the acridine orange-crystal violet staining of intracellular bacteria, microsporidian spores, and cytological smears.
