Description
- Highly hydrophilic, thiol-reactive fluorescent label containing one reactive maleimide group.
Applications
- Covalent labeling of proteins, thiol-modified DNA and thiol-modified oligonucleotides
- Fluorescence Lifetime Label — this label exhibits a distinct lifetime change upon binding to a biomolecule
- Fluorescence Resonance Energy Transfer (FRET) applications
- Single Molecule Applications — Seta-670 shows extreme low blinking in single molecule measurements
- Flow Cytometry
- Immunofluorescence
- Gene Expression
- Homogeneous Assays
- Assessment of protein structure
Advantages
- Perfectly suited for excitation with the 380, 404, 635, 670-nm diode lasers, LEDs, and UV light
- Sensitive; high extinction coefficients and high quantum yields up to 50% after covalent attachment to proteins
- Quantum yield is increased when covalently and non-covalently bound to protein
- pH-insensitive between pH 3 and pH 10
- Good aqueous solubility; this label does not alter the solubility of the protein conjugate
- 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 DNA probes and thiol-modified oligonucleotides
