Visualize Cell Dynamics with DiO: The Classic Lipophilic Tracer
Biotium’s DiO stain offers a reliable and versatile option for labeling cell membranes in your research. This green fluorescent, lipophilic carbocyanine dye is a well-established tool for tracing cellular movement and interactions.
Key Features of DiO:
- Widely Used Tracer: DiO is a popular choice for lipophilic tracing experiments due to its well-documented performance and ease of use.
- Bright Green Fluorescence: The λEx/λEm maxima at 484/501 nm provides clear and distinct labeling for accurate image analysis.
- Compatible with DiI: Combine DiO with DiI for dual-color labeling and colocalization studies, expanding your experimental capabilities.
- Multiple Formats: Choose from the versatile DiO powder or the ready-to-use CellBrite™ Green solution for simplified workflow integration.
Please note:
- DiO exhibits lower solubility and a slower lateral diffusion rate compared to newer alternatives like Neuro-DiO.
- For applications requiring superior solubility and faster diffusion, consider exploring Neuro-DiO (Product #60015).
DiO Applications:
- Live cell imaging of cell migration and morphology
- Investigating cell-cell interactions
- Monitoring neurite outgrowth
- Multicolor colocalization studies (in combination with DiI)
