Optimised for assays in which biotinylated protein is captured by streptavidin immobilized on a surface.

Cytiva Amersham™ Cy™3, Cy™ 5 Maleimide mono-Reactive Dye 5-packs

More selective method of antibody labeling that reduces the possibility of the label interfering with subsequent antibody-antigen reactions. Amersham™ Cy™3, Cy™ 5 Maleimide mono-Reactive Dye packs are packaged in premeasured amounts and foil-sealed to ensure consistent labelings.

Cytiva DeStreak Rehydration Solution

Highly suitable for both analytical and preparative gels. DeStreak Rehydration Solution improves reproducibility and quality of 2-D gels by preventing streaking.

Cytiva Cy™3B Mono-reactive NHS Ester Fluorescent Dyes

Combines exceptional photostability with bright and intense signals. Cytiva Cy™3B NHS Ester Mono-Reactive CyDye™ provides targeted and specific labeling of amine residues on antibodies, peptides, or oligonucleotides in fluorescence polarization applications.
