The Amersham Cy3 Maleimide Mono-Reactive Dye 5-Pack (PA23031) is a Cy3 maleimide dye pack for labelling biological compounds with Cy3 monofunctional dye. Each pack contains five vials of dye, with each vial sufficient to label 1 mg of protein. It is designed for selective labelling through thiol maleimide coupling when amine labelling with CyDye NHS esters is unsuitable.
Key Features
- Cy3 maleimide mono-reactive chemistry, designed for selective labelling through free sulfhydryl groups
- Five premeasured dye vials, with each vial sufficient to label 1 mg of protein
- Foil-sealed packaging, supporting consistent labelling from vial to vial
- Selective antibody labelling approach, helping reduce the chance of interference with antibody-antigen reactions
- Alternative to NHS ester labelling, suitable when amine labelling is not desirable or appropriate
- Water-soluble dye format, listed as soluble in cold water and hot water
- Molecular weight of 791 g/mol, as listed for the Cy3 maleimide dye
Benefits
- Supports selective labelling of proteins, peptides and oligonucleotides containing free sulfhydryl groups.
- Helps place the dye away from antibody binding sites, supporting retained antibody functionality.
- Premeasured vials reduce weighing and aliquoting steps in routine labelling work.
- Provides an option when NHS ester chemistry is not suitable for the sample or protocol.
