Spectra Viewer

Use this spectral viewer to see the excitation and emission spectra for all popular dye ranges (including Janelia Fluor® dyes and BDY dyes). It can be used to assess multiplexing options and suitable dye-antibody conjugate options. Note: absorption spectra may be displayed instead of excitation spectra.

Featured Dye Range

Janelia Fluor® (JF) dyes are bright, cell permeable and highly photostable small molecule fluorophores, which make them the perfect choice for live-cell imaging and super-resolution microscopy techniques, as well as flow cytometry, ICH and IHC. Janelia Fluor® dyes are supplied with a choice of reactive groups including click handles (tetrazine and azide), free acid, maleimide, and NHS ester (SE), allowing for simple biomolecule conjugation.

Janelia Fluor® dyes are conveniently compatible with popular self-labeling tag systems e.g. HaloTag® and SNAP-tag®.

With narrow absorption/emission spectra spanning across the color spectrum Janelia Fluor® dyes are perfect for multiplexing from green/yellow Janelia Fluor® 525, to the far red Janelia Fluor® 669.
