Zepto Ultra Fluorescent Microspheres

Zepto Ultra Microspheres Bead Mix MicroscopeCytodiagnostics Zepto™ Ultra Fluorescent Microspheres are optically encoded with unique fluorescent labels with several advantages over classical fluorescent dye labeled beads such as reduced propensity for photobleaching, narrower emission peaks and improved multiplexing capabilities.

Beads are available with two different surface chemistries, i.e. carboxylated and with a patent pending metal-coat for conjugation of biological molecules using carbodiimide coupling chemistry and straightforward high affinity adsorption, respectively.


  • Single Excitation Source for Multiple Colors
  • Sharp Emission Peaks (FWHM=30nm)
  • Extremely Bright and Photostable
  • Ideal for Multiplex Assay Development
  • Straightforward Conjugation of Biological Molecules
