The Amersham Cy7 Bis NHS Ester Reagent, 5 mg (PA17000) is a CyDye bis-reactive NHS ester fluorescent dye supplied as a 5 mg dried dye pack. This purple Cy7 labelling reagent is suitable for general labelling of amine residues, including protein amine groups, and supports fluorescence workflows such as ELISA, immunoprecipitation, blotting and high-throughput screening.
Key Features
- Cy7 bis-reactive NHS ester chemistry, suitable for general labelling of protein amine groups
- Two reactive groups per dye molecule, supplied in foil packs containing dried dye
- 5 mg value pack format, confirmed as product code PA17000 for this variant
- Purple Cy7 fluorescent dye, with excitation maximum at 743 nm and emission maximum at 767 nm
- High molar extinction coefficient, specified at approximately 200000 M^-1 cm^-1
- Biologically suitable pH range, with CyDye fluors supporting use across pH 3 to 10
- Multiplexing-ready dye family, using narrow excitation and emission bands to help minimise crosstalk
- Light-sensitive reagent format, requiring refrigerated storage at 2°C to 8°C, protected from light
Benefits
- Supports fluorescent labelling of proteins, antibodies, drugs and oligonucleotides for biochemical assay workflows.
- Helps laboratories prepare Cy7-labelled materials for ELISA, immunoprecipitation, blotting and screening applications.
- The bis-reactive format is useful when general amine-residue labelling is required.
- The 5 mg pack size provides a practical option for laboratories using Cy7 dye in smaller or controlled labelling work.
