Description

  • Highly hydrophilic, amine-reactive label containing one NHS-ester group.

 

Applications

  • Covalent labeling of proteins, amino-modified DNA and amino-modified oligonucleotides
  • Fluorescence intensity and fluorescence polarization-based applications
  • Resonance Energy Transfer (RET)
  • Flow Cytometry
  • Immunofluorescence
  • Gene Expression
  • Homogeneous Assays
  • Assessment of protein structure

 

Advantages

  • Perfectly suited for excitation with the 635 nm diode lasers
  • Sensitive; high extinction coefficients and high quantum yields after covalent attachment to biomolecules
  • Quantum yield is highly increased after covalent and non-covalent association with proteins
  • pH-insensitive between pH 3 and pH 10 
  • Good aqueous solubility; this label does not alter the solubility of the bioconjugate 
  • High photostability; e.g. compared to fluorescein or Cy5TM
  • Low molecular weight  — Seta dyes do not add substantial mass to the conjugates 
  • Ideal for non-radioactive labeling of proteins, amino-modified oligonucleotides and amino-modified lipids
