iFluor® 594 azide

Product key features

  • Bright, Red-Emitting Fluorophore: Excitation/emission maxima at ~588/604 nm, spectrally compatible with Texas Red® and Alexa Fluor® 594.
  • pH-Independent Fluorescence: Maintains stable emission across a broad pH range, ensuring reproducibility in diverse experimental conditions.
  • High-Specificity Bioconjugation: Azide functionality enables efficient and selective CuAAC-mediated labeling with alkyne-modified targets.
  • Low Background Signal: CuAAC chemistry minimizes nonspecific interactions, enhancing signal-to-noise ratio.
  • Broad Experimental Utility: Optimized for fluorescence microscopy, flow cytometry, and other fluorescence-based assays.

Product description

iFluor® 594 azide is a hydrophilic, red-emitting fluorescent dye engineered for efficient biomolecular labeling via click chemistry. It exhibits excitation and emission maxima at approximately 587 nm and 603 nm, respectively, aligning closely with dyes such as Texas Red® and Alexa Fluor® 594. A key advantage of iFluor® 594 is its pH-independent fluorescence, which remains stable across a broad pH range, ensuring consistent performance in different experimental conditions and improving reproducibility across diverse labeling applications.

The azide functionality of iFluor® 594 allows for precise and efficient bioconjugation with alkyne-functionalized molecules via copper-catalyzed azide-alkyne cycloaddition (CuAAC). Unlike conventional labeling strategies that modify amine or thiol groups, CuAAC provides exceptional chemoselectivity, minimizing nonspecific interactions and reducing background fluorescence. This improves labeling accuracy while maintaining the structural and functional integrity of biomolecules. iFluor® 594 azide is particularly suitable for applications including fluorescence microscopy, flow cytometry, and various fluorescence-based assays, providing researchers with a reliable tool for sensitive detection and imaging.
