The Amersham Cy5 Bis NHS Ester Reagent, 5 mg (PA15000) is a CyDye Value Pack fluorescent reagent for general labelling of protein amine groups. This Cy5 bis-reactive NHS ester format carries two reactive groups on each dye molecule and supports bright, photostable fluorescence across a biologically suitable pH range of 3 to 10. It is suited to protein labelling workflows used in immunoassays, immunoprecipitation, and medium to high-throughput fluorescence imaging.
Key Features
- Cy5 bis-reactive NHS ester format, supplied as a 5 mg pack for protein labelling workflows
- Two reactive groups per dye molecule, designed for general labelling of protein amine groups
- Bright and photostable CyDye fluorescence, supporting sensitive and reproducible detection
- Biologically suitable pH range, with performance stated across pH 3 to 10
- Multiplex-friendly signal behaviour, using narrow excitation and emission bands to help separate fluorescent signals
- Aqueous buffer solubility, simplifying preparation without the need for organic solvents
Benefits
- Supports reliable fluorescent protein labelling where sensitivity and reproducibility are important.
- Helps suit ELISA, immunoprecipitation, and fluorescence imaging applications using CyDye labelling strategies.
- Enables clearer multicolour assay design by reducing signal overlap between compatible CyDye fluors.
- Provides a convenient 5 mg pack size for laboratories selecting Cy5 bis NHS ester for amine-reactive labelling.
