Thermo Fisher, Q21541MP, Qdot™ 525 ITK™ Amino (PEG) Quantum Dots

Qdot™ 525 ITK™ Amino (PEG) Quantum Dots Qdot™ 525 ITK™ amino (PEG) quantum dotsare the ideal starting material for preparing custom conjugates of ultrabright and photostable fluorescently labeled proteins or other biopolymers. These probes are functionalized with amine-derivatized PEG, which prevents non-specific interactions and provides a convenient handle for conjugation. The amino quantum dots react efficiently with isothiocyanates and succinimidyl esters, or with native carboxylic acids using water-soluble carbodiimides such asEDC. Such derivatives may be used for various labeling and tracking applications that require ultrabright and stable fluorescence. Our Qdot™ ITK™ amino quantum dots are provided as 8 μM solutions and are available in 8 colors of Qdot™ probes.
Important Features of Qdot™ ITK™ Amino Quantum Dots:
• Qdot™ 525 ITK™ amino quantum dot has emission maxima of ∼525 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 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 amine-derivatized form, we offer Qdot™ ITK™ quantum dots with carboxyl 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.
