Molecular Probes™ Qdot™ 545 ITK™ Carboxyl Quantum Dots

Description

• Qdot™ 545 ITK™ carboxyl quantum dots are 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 using EDC -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 8μM 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 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 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
