FLR-68: Properties and Characteristics

FLR-68 boasts several key properties that contribute to its versatility:

Excitation/Emission: FLR-68 exhibits a specific excitation and emission spectrum (this data would need to be added from the dye's datasheet). This spectral profile is crucial for selecting appropriate filter sets in microscopy and flow cytometry.
Brightness: Its high quantum yield results in bright fluorescence, enabling sensitive detection even at low concentrations. This is particularly advantageous when working with limited samples.
Photostability: FLR-68 demonstrates superior resistance to photobleaching compared to some other dyes. This extended stability is vital for long-term experiments requiring sustained fluorescence.
Specificity: While inherently useful, the specificity of FLR-68 depends entirely on its conjugation to a targeting molecule. This could be an antibody, aptamer, or other ligand. Appropriate conjugation is crucial for specific labeling and is a critical factor in experimental design.
