Fluorescent Dye-Labeled Peptides
Our Offer
A peptide can be labeled with a single or multiple dye(s) at the peptide N-terminus, terminal C, or internally, for applications in protein interaction studies, to trace the presence of biomolecules in células, enzyme activity assays, etc..
For peptides labeled with a dye and quencher, see our FRET peptides page.

Our fluorescent dyes span the whole visible and near infrared spectrum
HiLyte™ Fluor Dyes (pH insensitive)
HiLyte™ Fluor dyes are ideal for applications at high or low pH (11). These dyes also exhibit higher sensitivities, owing to their enhanced intensity and photostability.

Fluorogenic Substrates
Fluorogenic substrates do not require a quencher and contain a C-terminal dye that does not fluoresce until it is cleaved from the peptide (fluorescent form of dye is released).
