Molecular Probes Qdot 655 ITK™ Amino (PEG) Quantum Dots

Product Overview

Qdot™ 655 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 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 8μM solutions and are available in 8 colors of Qdot™ probes.
