Minimize spectral overlap/spread and clearly distinguish cells populations with low antigen density. We offer a wide variety of fluorochromes across multiple lasers line for flow cytometry. To help you choose the right fluorochromes for your experiments, we have developed a fluorochrome atlas that allows you to view and compare dyes with attributes such as excitation/emission spectra, filter recommendations and relative resolution information.

BD Pharmingen™ PE (Ex Max  496 nm and 566 nm /Em Max 576 nm), R-phycoerythrin (PE), is an accessory photosynthetic pigment found in red algae. It exists in vitro as a 240-kDa protein with 23 phycoerythrobilin chromophores per molecule.  PE is designed to be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26 nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of blue, green and yellow-green lasers.

BD Horizon™ PE-CF594

BD Horizon PE-CF594 (PE-CF594) (Ex Max 496 nm and 566 nm/Em Max 615 nm) is a tandem conjugate that combines PE and CF594. PE-CF594, driven by BD innovation, is designed to be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and detected using an optical filter centered near 615 nm (e.g., a 610/20 nm bandpass filter). The donor dye can be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and the acceptor dye can be excited by the green (532 nm) laser resulting in cross-laser excitation and fluorescence spillover. PE-CF594 is a brighter alternative to PE-Texas Red, with improved spectral characteristics. PE-CF594 reagents exhibit very consistent spillover values lot-to-lot, making them an ideal choice for the PE-Texas Red detector (610/20 nm).

BD Pharmingen™ PE-Cy5

BD Pharmingen™ PE-Cy5 (PE-Cy5) (Ex Max 496 nm and 566 nm/Em Max 670 nm) is a tandem conjugate that combines phycoerythrin and a cyanine dye. PE designed to be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and detected using an optical filter centered near 670 nm (e.g., a 670/20 nm bandpass filter). The donor dye can be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and the acceptor dye can be excited by the red (627-640 nm) laser resulting in cross-laser excitation and fluorescence spillover. Because of its broad absorption range and the fact that its emission spectrum is equivalent to APC, PE-Cy5 is not recommended for simultaneous use with APC. The Cy5 molecule has been shown to exhibit nonspecific binding to Fc receptors, which is most apparent on monocyte populations. PE-Cy5 is not recommended for fluorescence microscopy because it is subject to photobleaching.

BD Pharmingen™ PE-Cy7

BD Pharmingen™ PE-Cy7 (PE-Cy7) (Ex Max 496 nm and 566 nm/Em Max 781 nm) is a tandem fluorochrome that combines PE and a cyanine dye. PE can be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and detected using an optical filter centered near 781 nm (e.g., a 760/60 nm bandpass filter). The donor dye can be excited by the blue (488 nm), green (532 nm) and yellow-green (561 nm) lasers and the acceptor dye can be excited by the red (627-640 nm) laser resulting in cross-laser excitation and fluorescence spillover. PE-Cy7 conjugated reagents are as bright as PE conjugates. PE-Cy7 is particularly sensitive to photo-induced degradation, resulting in loss of fluorescence and changes in fluorescence spillover. Extreme caution must be taken to avoid light exposure and prolonged exposure to paraformaldehyde fixative. Fixed cells should be analyzed within 4 hours of fixation in paraformaldehyde or transferred to a paraformaldehyde-free buffer for overnight storage.

BD Pharmingen™ APC

Allophycocyanin (APC) (Ex Max 651 nm/Em Max 660 nm) is an accessory photosynthetic pigment found in blue-green algae. Its molecular weight is approximately 105 kDa. APC has six phycocyanobilin chromophores per molecule, which make it a very bright fluorochrome that is highly suitable for flow cytometry applications. APC is designed to be excited by the red (627–640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter). Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor™ 647 cannot be used simultaneously.

BD Pharmingen™ Alexa Fluor™ 647

BD Pharmingen™ Alexa Fluor™ 647(Ex Max 653 nm/Em Max 669 nm) conjugates are highly photostable and remain fluorescent over a broad pH range. Alexa Fluor™ 647 is designed to be excited by the red laser (627–640 nm) and detected using an optical filter centered near 520 nm (e.g., a 660/20 nm bandpass filter). The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor™ 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor™ 647 cannot be used simultaneously.

BD Pharmingen™ APC-Cy7

BD Pharmingen™ APC-Cy7 (APC-Cy7) (Ex Max 651 nm/Em Max 782 nm) is a tandem fluorochrome that combines APC and a cyanine dye (Cy7). APC-Cy7 can be excited by the red (627–640 nm) laser and detected using an optical filter centered near 780 nm (e.g., a 760/60 nm bandpass filter). Special precautions must be taken with APC-Cy7 conjugates and cells stained with them to protect the fluorochrome from long-term exposure to light. Some APC-Cy7 conjugates show changes in their emission spectra with prolonged exposure to paraformaldehyde. Fixed cells should be analyzed within 4 hours of fixation in paraformaldehyde or transferred to a paraformaldehyde-free buffer for overnight storage.

BD Pharmingen™ APC-H7

BD Pharmingen™ APC-H7 (ACP-H7) (Ex Max 659 nm/Em Max 782 nm) is an APC-cyanine tandem fluorochrome, which uses an analog of Cy7 and has similar spectral properties to APC-Cy7. APC-H7 is designed to be excited by the red (627–640 nm) laser and detected using an optical filter centered near 780 nm (e.g., a 760/60 nm bandpass filter). APC-H7 conjugates provide greater stability in light and paraformaldehyde fixatives and have less spillover into the APC channel than APC-Cy7 conjugates. APC-H7 conjugates are typically 75% as bright as equivalent APC-Cy7 conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, APC-Cy7 and APC-H7 cannot be used simultaneously.
