CalFluor 647 Azide
This product is a far-red fluorescent dye containing an azide group. It specifically enables copper-catalyzed or copper-free click chemistry with alkynes, providing bright and photostable fluorescence for labeling, imaging, and probe development.
Key Features and Benefits
-
Azide Group: Reacts efficiently with alkynes via CuAAC or SPAAC click chemistry.
-
Far-Red Fluorescence: Emits strong signal (Ex/Em ≈ 646/664 nm).
-
Photostability: Provides reliable performance in long-term imaging experiments.
-
High Sensitivity: Detects low-abundance targets in microscopy, flow cytometry, and assays.
-
High Purity: Ensures reproducibility in sensitive labeling workflows.
Applications
-
Bioconjugation: Labels proteins, peptides, and nucleic acids through click chemistry.
-
Probe Development: Builds fluorescent probes for diagnostics and research.
-
Cell Imaging: Provides bright far-red signal for live or fixed cell studies.
-
Assay Development: Useful in FRET, ELISA, and fluorescence-based detection.
Storage and Handling
-
Storage: Store at –20 °C in a sealed, light-protected container.
-
Handling: Dissolve in DMSO or aqueous buffers; avoid repeated freeze–thaw cycles.
