Fluorescence and Dye Labeling Peptides

      Fluorescent dyes are the primary means of labeling biomolecules. The most common such dyes are FITC derivatives, which have a wide range of applications in fluorescence microscopy, flow cytometry, and immunofluorescence-based assays.
      TGpeptide provides many kinds of fluorescent labelings: FITC, FAM, TAMRA, MCA etc. Contact us if your fluorescent dye is not on the list.

FITC (Fluorescein isothiocyanate)

  • Color

    Ex(nm)

    Em(nm)

    Green

    495nm

    521nm

    FITC is usually use to label peptide and protein.

FAM

  • Color

    Ex(nm)

    Em(nm)

    Green

    492nm

    517nm

    FAM is usually use to laser confocal scanning microscopy and flow cytometry.

Rhodamine B

  • Color

    Ex(nm)

    Em(nm)

    Orange

    550nm

    580nm

    Rhodamine B is one of rhodamine dyes.

TAMRA

  • Color

    Ex(nm)

    Em(nm)

    Yellow

    544nm

    576nm

    TAMRA can send bright yellow light, and TAMRA has good stability.

NBD (7-nitrobenz -2- -oxa- -1,3-diazole)

  • Color

    Ex(nm)

    Em(nm)

    Green

    486nm

    543nm

    NBD is usually use in Cell-biology.

AMC

  • Color

    Ex(nm)

    Em(nm)

    Blue

    353nm

    422nm

    AMC is widely used in inspection of enzyme activities.

Cy3 and Cy5

  • Color

    Ex(nm)

    Em(nm)

    Cy3

    558nm

    572nm

    Cy5

    646nm

    664nm

    Cy3 and Cy5 are the dyes with high extinction coefficient, thus they are usually used at sensitive peptide location in cells, but they are not stable when we couple them to peptides, so the manufacture ammount is very small.
