Description

CyDye™ fluors are versatile fluorophores designed for a broad range of applications. CyDye™ fluors produce high sensitivity and highly reproducible performance at a biologically suitable pH range of 3 to 10. The use of multicolor CyDye™ flours enables multiplexing without crosstalk for high accuracy.

Cy™3B NHS Ester provides targeted and specific labeling of amine residues on antibodies, peptides, or oligonucleotides.

• Readily dissolves in and produces a stable signal in aqueous buffers (no need for organic solvents)
• High purity and thorough QC testing generate high levels of chromophore and reactive dye content
• Narrow excitation and emission bands result in discrete signals from each fluor
• Demonstrates larger polarization range than conventional fluors
• Fluorescence lifetime of 2.8 ns
• High fluorescence intensity
• Low non-specific binding
