Qdot® 545 ITK™ organic quantum dots are the ideal starting material for applications calling for organic solvents such as hexane, toluene, dichloromethane, or chloroform. These materials are provided as solutions in decane, and are not water soluble. These Qdot® ITK™ organic quantum dots are designed for researchers who want to use their own methods for transferring quantum dot materials into water. Our Qdot® ITK™ organic quantum dots are provided as 1 µM solutions and are available in 7 colors of Qdot® probes.

Important Features of Qdot® ITK™ Organic Quantum Dots:
• Qdot® 545 ITK™ organic quantum dot has emission maxima of ~545 nm
• Extremely photostable and bright fluorescence
• Efficiently excited with single-line excitation sources
• Narrow emission, large stokes shift
• Available in multiple colors
• Ideal for various labeling and tracking applications

Properties of Qdot® Nanocrystals
Qdot® probes are ideal for imaging and labeling applications that require bright fluorescent signals and/or real-time tracking. Unique among fluorescent reagents, all nine available colors of Qdot® probes can be simultaneously excited with a single (UV to blue-green) light source. This property makes these reagents excellent for economical and user-friendly multiplexing applications. Qdot® labels are based on semiconductor nanotechnology and are similar in scale to moderately sized proteins.

About the Innovator’s Tool Kit Qdot® ITK™ Reagents
These Qdot®ITK™ probes are ideal for researchers who wish to prepare specific (non-stocked) conjugates for their applications and need customizable conjugation functionality.

Other Forms of Qdot® Nanocrystals are Available
In addition to the organic form, we offer Qdot® ITK™ quantum dots with carboxyl and amine-derivatized PEG modifications. We’ve also developed a wide range of Qdot® nanocrystals conjugates and labeling kits. Investigate the properties of Qdot® nanocrystals or read the Molecular Probes® Handbook Section 6.6—Qdot® Nanocrystals to find out more.
