Sulfonated, water soluble version of Cyanine5 fluorophore, equivalent of Cy5®, a universal dye. Very bright dye with red emission. Most fluorescent instruments with filters have an appropriate channel for this dye.


Near infrared water soluble cyanine fluorophore, mainly useful for non-invasive in vivo imaging.


Borondipyrromethene dye for fluorescein (488 nm) channel - very bright and photostable fluorophore.


Borondipyrromethene fluorophore with absorption and emission spectra similar to TAMRA, but much brighter, and very photostable.

Coumarin 343

Coumarin 343 is a blue emitting fluorophore that forms a FRET pair with FAM as a donor.


Bright and extremely photostable polycyclic aromatic hydrocarbon fluorophore with the quantum yield approaching unity, especially useful for materials science, and supramolecular constructs.

Phenylethynyl-pyrene (PEP)

Phenylethynylpyrene (PEP) is a pyrene derivative with red-shifted absorption and emission spectra. Fits blue channel of qPCR instruments, can be used for multiplex experiments.


Pyrene is a fluorescent polycyclic aromatic hydrocarbon. It is useful as a proximity sensor - when two pyrene residues are spaced close to each other, they exhibit easily detectable excimer fluorescence.


BDP TR is a borondipyrromethene dye for ROX/Texas Red channel.


Sulfo-Cyanine5.5 is a sulfonated far red emitting fluorophore which is highly water-soluble and hydrophilic.


BDP R6G is a borondipyrromethene dye which is specially tuned to match excitation and emission channels of the classical rhodamine 6G dye. BDP R6G possesses a high extinction coefficient, and excellent quantum yield. The fluorophore is ideal for various labeling applications.


Sulfo-Cyanine7.5 is a water soluble near infrared fluorophore. Its absorption spectrum, structure, and hydrophilicity resemble indocyanine green (ICG), but it has a significantly higher fluorescence quantum yield. This dye is useful for non-invasive in vivo NIR imaging.

BDP 630/650

BDP 630/650 is a bright and photostable far red fluorophore. It possesses narrow absorption and emission peaks as well as high extinction coefficient and quantum yield. Its relatively long excited state lifetime and significant two photon cross section makes it ideal for two photon experiments, and for fluorescence polarization assays.

BDP 581/591

BDP 581/591 is a relatively hydrophobic borondipyrromethene fluorophore that can be used to probe reactive oxygen species (ROS), or as a fluorescence polarization tracer. It features high brightness, a significant two photon cross-section, and a relatively long fluorescence lifetime.
