Invitrogen™ Alexa Fluor™ Plus Amine-Reactive Dyes
Discover Alexa Fluor Plus amine-reactive dyes, the next-generation fluorescent labeling solution. Engineered to minimize nonspecific staining and enhance signal-to-noise ratios, these dyes ensure precise detection of low-abundance targets. Achieve bright, reliable imaging with reduced background interference.
Thermo Scientific™ EZ-Link™ DBCO Protein Labeling Kit
Kit provides everything needed to covalently label proteins with a dibenzylcyclooctyne (DBCO) group for copper-free click chemistry applications. Contains all necessary materials to perform five labeling reactions and subsequent purification for removal of excess DBCO reagent.
Invitrogen™ Biotin-X, SE (6-((Biotinoyl)Amino)Hexanoic Acid, Succinimidyl Ester (Biotinamidocaproate, N-Hydroxysuccinimidyl Ester))

MilliporeSigma™ Calbiochem™ β-Cyclodextrin
Homogeneous cyclic α1,4-linked D-glucopyranose units in a seven-member ring. Forms clathrates. Suitable for use with dansyl chloride to form water-soluble complexes for fluorescent labeling of proteins.
Cytiva Amersham™ CyDye™ Value Packs (bis-Reactive NHS Ester)
Suitable for general labeling of amine residues
Cytiva CyDye™ DIGE Fluor Minimal Dye Labeling Kits
Allow detection of up to three prelabeled protein samples and standards on the same 2-D electrophoresis gel. Amersham CyDye™ DIGE Fluor Minimal Labeling Kits contain size- and charge-matched fluorescent dyes specifically designed for detecting protein abundance differences in 2-D Fluorescence Difference Gel Electrophoresis using Ettan DIGE system.
Cytiva CyDye™ DIGE Fluors: Cy2
Allow detection of up to three prelabeled protein samples and standards on the same 2-D electrophoresis gel
Cytiva Amersham™ CyDye™ Value Packs (mono-Reactive Maleimide)
For the selective labeling of free sulfhydryl groups such as cysteine residues in peptides, proteins, and oligonucleotides
Cytiva Cy3 NHS Ester Mono-Reactive CyDye
Use for highly accurate labeling of amine groups. Cytiva Cy3 NHS Ester Mono-Reactive CyDye contain derivitized CyDyes that carry only one reactive group on each dye molecule for accurate labeling of amine groups, for example on antibodies, peptides, or oligonucleotides.
