Water soluble, amine-reactive fluorescent label containing one reactive NHS-ester group.
Applications
Covalent labeling of proteins, amino-modified DNA, and amino-modified oligonucleotides
Fluorescence Lifetime Label — this label exhibits a distinct lifetime change upon binding to a biomolecule
Resonance Energy Transfer (RET)
Flow Cytometry
Immunofluorescence
Gene Expression
Homogeneous Assays
Assessment of protein structure
Advantages
The dye is excitable with both UV-blue and red-NIR light sources and perfectly suited for excitation with 380-nm, 404-nm, 650-nm, 680-nm, and 700-nm LEDs and diode lasers
pH-insensitive between pH 4 and pH 9
Good aqueous solubility; this label does not alter the solubility of the protein conjugate
High photostability, e.g., compared to fluorescein or Cy5TM and Cy7TM
Low molecular weight — Seta dyes do not add substantial mass to the conjugates
Ideal for non-radioactive labeling of proteins, amino-modified probes, and amino-modified oligonucleotides
