Applications of 23491-45-4
| Industry | Application | Process |
|---|---|---|
| Biology | Nucleic acid staining | Used for visualization of DNA or RNA following agarose gel electrophoresis: gels containing samples are immersed in a solution of Hoechst 33258 dye, then visualized under UV illumination. |
| Molecular Biology | Nuclear labeling | Applied for fluorescent labeling of cells under microscopy to study cellular structure, leveraging the dye’s selective binding to nuclear DNA; typically requires cell fixation and permeabilization. |
| Microbiology | Colony counting | Applied to stain microbial colonies on culture media, enabling clearer identification and enumeration of individual colonies under UV light. |
| Environmental Science | Microbial indicator in water quality testing | Used as one method for rapid detection of specific bacterial types in water; water quality is assessed indirectly by measuring fluorescence intensity after staining. |

Stability |
Bulk: Under ordinary laboratory illumination, the material slowly decomposes. At the end of four weeks at room temperature in a capped glass vial, 3% decomposition has occurred (HPLC). In a similar container but maintained at 45 °C and in darkness, the subject sample was stable for at least four weeks (HPLC). Solution: A solution of the sample (1 mg/mL) is stable in water for at least 24 hours at room temperature under normal laboratory illumination. |
