Thermo Fisher, Q21391MP, Qdot™ 545 ITK™ Carboxyl Quantum Dots

Qdot™ 545 ITK™ Carboxyl Quantum Dots Qdot™ 545 ITK™ carboxyl quantum dotsare the ideal starting material for preparing custom conjugates that require high loading of biomolecules. These materials are carboxylate functionalized and can be coupled to amine groups of proteins and modified oligonucleotides usingEDC-mediated condensation. The coatings of these probes provides more binding sites than our Qdot™ ITK™ amino quantum dots, but lacks PEG linkers that help to prevent non-specific interactions. These materials can be conjugated to X-PEG-amine bi-functional linkers for custom reactivity and higher specificity. Our Qdot™ ITK™ carboxyl quantum dots are provided as 8 μM solutions and are available in all 9 Qdot™ probe colors.
Important Features of Qdot™ ITK™ Carboxyl Quantum Dots:
• Qdot™ 545 ITK™ carboxyl 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 labeling and tracking applicationsProperties of Qdot™ NanocrystalsQdot™ 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™ ReagentsThese 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 AvailableIn addition to the carboxyl-derivatized form, we offer Qdot™ ITK™ quantum dots with amino and aliphatic hydrocarbon modifications. We’ve also developed a wide range of Qdot™ nanocrystals conjugates and labeling kits. Investigate the properties ofQdot™ nanocrystalsor read the Molecular Probes™Handbook Section 6.
