Qdot Probes in Flow Cytometry
- Flexibility—excited by 405 nm or 488 nm, maximizing violet laser use
- Compatibility—combine with existing organic dyes, increase the number of detectable parameters
- Stability—does not degrade over time like tandem conjugates, for greater reproducibility
- Minimal single laser compensation—narrow emission spectra allow for minimal compensation when using a single excitation source
What are Qdot probes and how are they used in flow cytometry?

How Qdot probes benefit your flow cytometry
Greater flexibility and precision for flow cytometry
With new flow cytometry instrumentation allowing ever-expanding detection capabilities, Qdot probes add an exciting new array of fluorescent labels for use in flow cytometry. Qdot probes provide fluorescent labels that can be excited with UV or violet light as well as longer-wavelength light sources, and exhibit long effective Stokes shifts and relatively narrow emission peaks. The result: greater flexibility and precision in designing multicolor flow cytometry panels.
