- Flow cytometry
Handling and Storage
Store the product in a cool, dry place away from direct light. For long-term storage, keep it at 2–8°C. Always handle with appropriate lab safety measures, including gloves and eye protection, as it is a potent dye.
Why This Product Stands Out
Merck’s 5(6)-Carboxytetramethylrhodamine is preferred by researchers for its high quantum yield and resistance to photobleaching. Unlike other rhodamine derivatives, this variant offers better water solubility and reduced aggregation, ensuring clearer imaging results.
For students and educators, this dye serves as an excellent tool for teaching fluorescence principles and advanced microscopy techniques. Its stability under various experimental conditions makes it a reliable choice for both academic and industrial labs.
FAQs
What is the excitation and emission wavelength of this dye?
It typically has an excitation peak around 540–550 nm and an emission peak around 570–580 nm, depending on the solvent and pH.
Can this dye be used for in vivo imaging?
While it is primarily used for in vitro applications, its bright fluorescence makes it suitable for certain in vivo studies with proper controls.
Is this product soluble in water?
Yes, it has moderate water solubility but dissolves best in organic solvents like DMSO or ethanol for stock solutions.
What is the shelf life of this product?
When stored correctly, it remains stable for at least 2 years. Always check the certificate of analysis for batch-specific details.
