Activated Dyes

Activated Dyes

Interchim Activated Dyes combine the fluorescence intensity and photo-stability performance characteristics of FluoProbes® dyes with a range of activated formats for labelling your compounds of interest. Our most popular labels are highlighted below, other formats are available upon request.

NHS (1mg)

NHS-ester derivatives are suited for direct labeling of amino groups in proteins & DNA/RNA. The chemical group N-hydroxysuccinimidyl (NHS) reacts optimally at neutral / higher pH in aqueous phase on primary and secondary amines. NHS-esters should be moisture protected stored at 4°C, and are stable for at least one year.
