Product Overview
FA Rhodamine Counterstain is a high-performance fluorescent dye designed for precise counterstaining in microscopy applications. Its exceptional photostability and bright red fluorescence make it ideal for visualizing cellular structures with minimal photobleaching. The lab-grade formulation ensures consistent staining intensity, reducing background interference for clearer imaging results. Compatible with a wide range of fixation and permeabilization protocols, this counterstain integrates seamlessly into existing workflows without compromising sample integrity. The liquid form allows for easy dilution and uniform application, while its optimized spectral properties minimize overlap with other fluorophores. Whether used in single or multiplex staining, FA Rhodamine delivers reliable contrast and resolution, enhancing the accuracy of fluorescence-based analyses. Store at room temperature, protected from light, to maintain long-term stability and performance.
FAQs
1
What is the excitation/emission range of FA Rhodamine Counterstain?
FA Rhodamine typically excites around 540-550 nm and emits at 570-580 nm, making it suitable for standard TRITC filter sets.
2
Is this counterstain compatible with formaldehyde-fixed samples?
Yes, it works well with formaldehyde-fixed samples, but ensure proper permeabilization for optimal staining.
3
Can FA Rhodamine be used with other fluorescent dyes?
Yes, its spectral properties allow multiplexing with dyes like FITC or DAPI with minimal overlap.
4
How should I store this counterstain for long-term use?
Store at room temperature, away from direct light, in a tightly sealed container to prevent degradation.
5
What alternatives exist if FA Rhodamine is unavailable?
Texas Red or TRITC-based counterstains can serve as alternatives with similar excitation/emission profiles.
