Biotium, a supplier and inventor of fluorescent cellular probes for life science research, has announced the release of infrared CF850 and CF870 dyes.
The company said the long wavelength dyes are the first commercially available fluorescent dyes with emission maxima greater than 850 nm, allowing researchers to further investigate the 'final frontier' of infrared wavelengths for life science research applications, said the firm.
"Due to their excellent brightness, aqueous solubility, and exceptional infrared properties, CF850 and CF870 represent a true breakthrough in synthetic fluorescent probes."
Their sensitivity, linearity, tissue penetration, and minimal autofluorescence background are beneficial for in vivo imaging, western blotting, and microscopy, according to Biotium.
“Recently, the benefits of long wavelength fluorescence have spurred the development of flow cytometers and imaging instrumentation equipped with near-IR laser diodes and detection systems. Biotium’s CF850 and CF870 dyes aim to accommodate research that takes advantage of these hardware advancements by offering long wavelength emission beyond any commercially available IR probe.”
