Description

  • Highly hydrophilic, thiol-reactive label containing one maleimide group.

 

Applications

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

 

Advantages

  • Perfectly suited for excitation with the 635 and 647 nm diode laser
  • 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, thiol-modified oligonucleotides and thiol-modified lipids
