Cy7-Gly-Gly-Gly
This product is a near-infrared fluorescent dye conjugated with a tripeptide linker (Gly-Gly-Gly). The Cy7 moiety specifically enables highly sensitive fluorescence imaging in the near-infrared region, while the flexible tripeptide spacer improves solubility and provides a reactive handle for further bioconjugation.
Key Features and Benefits
-
Cy7 Dye – Emits in the near-infrared (NIR) spectrum (~750–800 nm) for deep-tissue imaging with low background autofluorescence.
-
Tripeptide Linker (Gly-Gly-Gly) – Enhances solubility, provides spacing, and offers sites for further conjugation.
-
High Photostability – Maintains signal intensity during extended imaging experiments.
-
Bioconjugation Ready – Suitable for coupling to biomolecules, nanoparticles, or surfaces.
Applications
-
In vivo and in vitro fluorescence imaging
-
Conjugation to proteins, peptides, and antibodies
-
Drug delivery and biodistribution studies
-
Optical probe development for diagnostics and theranostics
Storage & Handling
-
Storage: Store at –20 °C, dry, and protected from light.
-
Use: Dissolve in DMSO, DMF, or aqueous buffer (pH ~7–8). Avoid repeated freeze–thaw cycles.
