Description
- Highly hydrophilic, thiol-reactive fluorescent label containing one reactive maleimide group
Applications
- Covalent labeling of thiol-modified peptides, oligonucleotides, and proteins
- Fluorescence Lifetime Label — this label exhibits a distinct lifetime change upon binding to a biomolecule
- Fluorescence intensity and fluorescence polarization-based applications
Advantages
- Perfectly suited for excitation with the 635 nm diode lasers
- Sensitive; high extinction coefficients andhigh 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
- Low molecular weight — Seta dyes do not add substantial mass to the conjugates
- Ideal for non-radioactive labeling of thiol-modified proteins, peptides, and oligonucleotides
