Fluorescent Dye-Labeled Peptides
Our Offer
A peptide can be labeled with a single or multiple dye(एस) at the peptide N-terminus, सी टर्मिनल, or internally, for applications in protein interaction studies, to trace the presence of biomolecules in कोशिकाओं, 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.
| Name | Abs/Em | Applications | |
|---|---|---|---|
| HiLyte™ Fluor 488 | • | 497/525 एनएम | FRET Assays, tracing or interaction studies |
| HiLyte™ Fluor 555 | • | 550/566 एनएम | FRET, लेबलिंग |
| HiLyte™ Fluor 647 | • | 650/675 एनएम | FRET/TR-FRET, लेबलिंग |
| HiLyte™ Fluor 750 | • | 753/778 एनएम | Imaging |
Classical Dyes
Classical dyes such as FAM, TAMRA and the CyLyte Fluor dyes (Cy Dyes analogues) are a great cost-effective choice when operational pH range of your application is flexible.®

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).

|---|---|---|---|
| AMC | • | 351/430 एनएम | Fluorogenic substrates |
| AFC | • | 382/480 एनएम | Fluorogenic substrates |
| Rh110 | • | 501/527 एनएम | Fluorogenic substrates |
