Hexidium iodide, a fluorescent nucleic binding acid stain (excitation/emission ~ 518/600 nm), permeants to mammalian cells and selectively stains almost all gram-positive bacteria. Hexidium iodide can bind to the DNA of all bacteria after permeabilization by EDTA.
In Vitro
Hexidium iodide allows assessment of Gram status by differential absorption through bacterial cell walls, selectively staining gram-positive organisms in suspension. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

生化机理
碘化铯是一种荧光核结合酸染色剂(激发/发射 ~ 518/600 纳米),可渗透到哺乳动物细胞,并可选择性染色几乎所有革兰氏阳性细菌。碘化铯渗透后可与所有细菌的 DNA 结合
