The CyDye Cy5 Maleimide Reagent, 5 mg (PA15130) is a mono-reactive Cy5 maleimide dye supplied as a 5 mg dried dye pack. This fluorescent labelling reagent is designed for selective labelling of free sulfhydryl groups, including cysteine residues in peptides, proteins and oligonucleotides.
Key Features
- Mono-reactive Cy5 maleimide chemistry, designed for labelling compounds that contain free thiol groups
- Selective sulfhydryl-group labelling, suitable for cysteine residues in peptides, proteins and oligonucleotides
- Particularly suitable for antibody labelling, with dye molecules introduced away from the antibody binding site
- 5 mg dried dye pack, supplied as a pre-measured format for laboratory labelling workflows
- Blue Cy5 dye format, supporting fluorescent detection with suitable Cy5 filter sets
- Reconstitution-ready format, with instructions for preparing material at 1 mg/mL in anhydrous DMF or DMSO
- Example protocols included, helping laboratories set up thiol-reactive labelling workflows
Benefits
- Supports targeted fluorescent labelling of thiol-containing biomolecules for protein analysis workflows.
- Helps preserve antibody functionality by introducing dye away from the binding site.
- The pre-measured dried dye format supports convenient preparation and controlled reagent handling.
- Suitable for laboratories working with antibodies, peptides, proteins or thiol-modified oligonucleotides.
