Qdot® Nanocrystals

Qdot® nanocrystals represent a truly enabling "nanotechnology" and offer revolutionary fluorescence performance including:

  • Long-term photostability for live-cell imaging and dynamics studies
  • Brilliant colors for simple, single-excitation multicolor analysis
  • Fixability for follow-up immunofluorescence after in vivo studies
  • Narrow, symmetrical emission spectra for low interchannel crosstalk

New Qdot® Products

Qmount™ Qdot® Mounting Media

Qmount™ Qdot® Mounting Media
This new Qdot® addition preserves the fluorescence signal of Qdot® nanocrystals with little to no loss of the signal’s intensity both initially and over the course of several months.

 
Qnuclear™ Deep Red Stain
Qnuclear™ Deep Red Stain
A bright and photostable nuclear counterstain designed for use with cells labeled with Qdot® nanocrystals and mounted in Qmount™ Qdot® mounting media.

Applications



Qdot® nanocrystals and bioconjugates are ideal for experiments requiring long-term photostability or single-excitation, multicolor analysis.

 

Structure of a Qdot® Nanocrystal
Structure of Qdot® Nanocrystals

Fundamentally, Qdot® nanocrystals are fluorophores—substances that absorb photons of light, then re-emit photons at a different wavelength.

Relative Size and Tuneability
Qdot® Size and Tuneability

There is a predictable relationship between the physical size of the quantum dot and the wavelength of emitted fluorescence. This property has been referred to as "tuneability", and is being widely exploited in the development of multicolor assays.
