Fluorescent Dyes for the Green and Yellow/Green Lasers

The table below lists the properties of the most commonly used fluorophores for the green laser. To see a list of available conjugated antibodies to your fluorophore of interest, click on the fluorophore name in the table.

 
Green and Yellow/Green Laser Fluorescent Dyes - 532 - 561 nm Excitation
Name Excitation (nm) Peak Emission (nm) Relative Intensity
(1 = Lowest,
5 = Highest)
Uses

Alexa Fluor® 532

532 561 3

Detected in channel with appropriate filter set arrangement for the instrument.

Photostable and pH independent.

An excellent choice for fluorescence microscopy.

R-PE (R-Phycoerythrin) 532 - 561
578 5

Detected in FL2 channel on most instruments.

High quantum yield (ideal for detection of low density antigens).

Subject to photobleaching.

PE-Texas Red

(Not available from eBioscience)

532 - 561
615 3 Detected in FL3 on single laser instruments.
PE-Cy5 532 - 561
667 4

Detected in FL3 or FL4 on most instruments.

Tandem dye, resonance energy transfer from PE molecule to the cyanine dye Cy5.

When used with APC on dual laser machines, needs a cytometer capable of interlaser compensation. See PE-Cy5.5 for dual laser instruments.

PE-Cy5.5

532 - 561
695 3 to 4

Detected in FL3 or FL4 on most instruments.

Tandem dye, resonance energy transfer from PE molecule to cyanine dye Cy5.5.

When used with APC on dual laser machines, needs a cytometer capable of interlaser compensation. Better choice for dual laser instruments than PE-Cy5.

PE-Cy7 532 - 561
785 3

Detected in channel with appropriate filter set arrangement for the instrument.

Tandem dye, resonance energy transfer from PE molecule to cyanine dye Cy7.

Minimal cross-beam compensation required when used simultaneously.
