How to Use
Nile Red is a hydrophobic dye and is typically insoluble in water. To prepare for use, dissolve the solid reagent in an appropriate organic solvent such as DMSO, ethanol, or acetone to create a concentrated stock solution. For fluorescence microscopy or flow cytometry, dilute the stock solution into your working buffer or medium.
When staining, apply the solution to the sample and allow for an incubation period as dictated by your specific protocol. Because this reagent is used for fluorescence analysis, a fluorescence microscope or spectrofluorometer is required for detection. Adjust excitation and emission settings based on the polarity of the environment, as Nile Red’s fluorescence properties shift depending on the hydrophobicity of its surroundings.
Care & Safety
- Storage: Store in a cool, dry, and well-ventilated area.
- Light Sensitivity: This reagent is sensitive to light. Keep the container tightly sealed and protected from direct light exposure to prevent photodegradation.
- Handling: Always wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Avoid inhalation of dust and direct contact with skin or eyes.
- Professional Use: Intended for laboratory research and analytical purposes only.
