伊文斯兰（Evans blue）在该染料中用作复染剂，当使用蓝色光激发（并非UV）检测可降低组织和血细胞内的背景荧光信号。300-440nm的光谱范围（Emax=433nm0.1M磷酸盐pH 7.0；纤维素）可用作发射光谱，激发波长约在355nm。卡尔科弗卢尔白M2R（Calcofluor White M2R ） 1 g/L 伊文斯兰（Evans blue） 0.5 g/L 真菌或寄生生物呈亮绿到蓝色荧光，而其他材料呈红-橙色荧光。若染色组织样本会有非特异性反应。对于这些样本可能会看到黄绿色背景荧光，但真菌和寄生结构荧光强度更明亮。 Fungal or parasitic organisms appear fluorescent bright green to blue, while other material is reddish-orange fluorescent. Non-specific reactions may occur when tissues samples are used. May a yellowish-green background. fluorescence is observed with such specimens but fungal ａnd parasitic structures appears with much more intense. Attention cotton fibers will fluoresce strongly ａnd must therefore be differentiated from fungal hyphae. As well amebic cysts are fluorescent but trophozites will not stain or fluoresce, Background fluorescence can be diminished by examining under blue light or by using different filter combinations (emission ａnd excitation filters）. One ｄrop of 10% potassium hydroxide solution can be added for better visualization of fungal elements. 另提供所有产品仅用于科研实验；
