Excitation and emission spectra can be found below.
Bright Fluorescent Particles
Our Bright Fluorescent Particles are uniform polystyrene-based nanospheres and microspheres that are made with fluorescent dyes. We offer four different colors (Yellow-Green, Red, Blue, and Orange) with either unmodified, carboxylated, or aminated functional groups.
These fluorescent beads are used for tracking and visualization applications that require high-intensity fluorescence. Some common applications include stem cell labeling, filtration system testing, and fluorescent particle imaging velocimetry. For flow cytometry applications, please see our Flow Cytometer Beads (provide link).
The excitation and emission spectra for our fluorescent beads are shown below.

Magenta Fluorescent Particles
Our Magenta Fluorescent Particles are uniform polystyrene-based nanospheres and microspheres that produce a high quantum yield. They are offered with either unmodified, carboxylated, or aminated functional groups. Magenta Fluorescent Particles can be excited with either a UV laser or a 640 nm laser.
