Methylene Violet 3RAX 是一种阳离子染料,是光动力疗法中的潜在光敏剂,具有抗肿瘤活性,能够改变 DNA 的分子结构,破坏 DNA 的模块,诱导活性单线态氧的产生,用于染色细胞的线粒体。Methylene Violet 3RAX 抑制亚细胞定位癌细胞,通过切断肿瘤细胞中的 DNA 链导致细胞死亡。
Hexidium iodide is a fluorescent nucleic acid stain that selectively permeates mammalian cells and exhibits excitation/emission at approximately 518/600 nm. This compound effectively stains nearly all gram-positive bacteria. Upon permeabilization using EDTA, Hexidium iodide can bind to the DNA of all bacterial species.
Phalloidin-FITC is a green fluorescent cytoskeleton stain. Binds and labels F-actin. For most fluorescent imaging applications, cells should be fixed and permeablilized. Excitation/emission maxima λ ~496/516 nm.
Patent Blue V(Acid blue 1)是一款应用于眼科的新型生物染料,特别是在进行视网膜切除手术时,用以染色以便去除内限制膜(ILM)。该染料在玻璃体视网膜手术中确保了对视网膜结构的有效标记,从而实现精确去除。光谱分析揭示,Patent Blue V在450 nm以下和600 nm以上具有强烈的吸收特性,展现蓝绿色。此外,它亦作为淋巴管造影术中的追踪剂,在染色活检手术中使用以助于淋巴结的切除。
