Qdot™ 605 ITK™ amino (PEG) quantum dots are 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 as EDC. 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™ 605 ITK™ amino quantum dot has emission maxima of ∼605 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 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 of Qdot™ nanocrystals or read the Molecular Probes™ Handbook Section 6.6—Qdot™ Nanocrystals to find out more.

Abstract
Development of homogeneous binding assays based on fluorescence resonance energy transfer between quantum dots and Alexa Fluor fluorophores.
Journal:Anal Biochem
PubMed ID:16860286
'We studied the fluorescence resonance energy transfer (FRET) between quantum dots emitting at 565, 605, and 655 nm as energy donors and Alexa Fluor fluorophores with absorbance maxima at 594, 633, 647, and 680 nm as energy acceptors. As a first step, we prepared covalent conjugates between all three types
Quantum dot targeting with lipoic acid ligase and HaloTag for single-molecule imaging on living cells.
Journal:ACS Nano
PubMed ID:23181687
'We present a methodology for targeting quantum dots to specific proteins on living cells in two steps. In the first step, Escherichia coli lipoic acid ligase (LplA) site-specifically attaches 10-bromodecanoic acid onto a 13 amino acid recognition sequence that is genetically fused to a protein of interest. In the second
Quantum dots provide an optical signal specific to full collapse fusion of synaptic vesicles.
Journal:Proc Natl Acad Sci U S A
PubMed ID:17968015
Synaptic vesicles are responsible for releasing neurotransmitters and are thus essential to brain function. The classical mode of vesicle recycling includes full collapse of the vesicle into the plasma membrane and clathrin-mediated regeneration of a new vesicle. In contrast, a nonclassical mode known as
Novel system to achieve one-pot modification of cargo molecules with oligoarginine vectors for intracellular delivery.
Journal:Bioconjug Chem
PubMed ID:19161253
There is a growing number of reports showing the usefulness of cell-penetrating peptides (CPPs) including oligoarginines for intracellular delivery of macromolecules. Although the covalent attachment of the CPP segments to the cargo molecules is usually required to ensure effective delivery, conventional methods of conjugation need several manipulation steps that are
Optical coding of mammalian cells using semiconductor quantum dots.
Journal:Anal Biochem
PubMed ID:15051536
Cell-based assays are widely used to screen compounds and study complex phenotypes. Few methods exist, however, for multiplexing cellular assays or labeling individual cells in a mixed cell population. We developed a generic encoding method for cells that is based on peptide-mediated delivery of quantum dots (QDs) into live cells.
