We regularly update this area of the site, so check back often for updates! A user arriving at the Dye Directory landing page will be presented with an interface allowing them to search for fluorophores based on a variety of characteristics.  The following filters may be used together or individually to narrow fluorophore search results: **Fluorophore name **- searching for a fluorophore by name will return results matching (or partially matching) your entered search term.   ![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-06-24-2011-PM.png?width=688&height=229&name=image-png-Jul-24-2025-03-06-24-2011-PM.png) **Excitation Range** - specifying a range of excitation wavelengths will provide results of fluorophores that have peak excitations within the specified range  ![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-08-12-1207-PM.png?width=688&height=383&name=image-png-Jul-24-2025-03-08-12-1207-PM.png) **Emission Range** - specifying a range of emission wavelengths will provide results of fluorophores that have peak emissions within the specified range  ![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-09-00-3807-PM.png?width=688&height=379&name=image-png-Jul-24-2025-03-09-00-3807-PM.png) **Letter Filters - **clicking any of the individual letter filters (depicted below) will show only those fluorophores that begin with the chosen letter.  In the image below, 'A' has been selected: ![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-11-17-6809-PM.png?width=688&height=248&name=image-png-Jul-24-2025-03-11-17-6809-PM.png) **Reset Filters - **clicking this button will reset any filters you've already applied Clicking the name (![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-12-15-6833-PM.png?width=128&height=22&name=image-png-Jul-24-2025-03-12-15-6833-PM.png)) or "Details" button (![](https://help.fluorofinder.com/hs-fs/hubfs/image-png-Jul-24-2025-03-12-32-6819-PM.png?width=72&height=28&name=image-png-Jul-24-2025-03-12-32-6819-PM.png)) next to a fluorophore's entry will open a page containing more details about the associated fluorophore (see "[Dye Directory - Fluorophore Entries](https://help.fluorofinder.com/dye-directory-fluorophore-entries?hsLang=en)" for more details - [Getting Started](https://help.fluorofinder.com/getting-started?hsLang=en) - [Flow Cytometry Panel Builder Help Files](https://help.fluorofinder.com/flow-cytometry-panel-builder-help-files?hsLang=en#main-content) - [Panel Builder Guides](https://help.fluorofinder.com/flow-cytometry-panel-builder-help-files?hsLang=en#panel-builder-guides) - [How To Guides](https://help.fluorofinder.com/flow-cytometry-panel-builder-help-files?hsLang=en#how-to-guides) - [Interpreting Data](https://help.fluorofinder.com/flow-cytometry-panel-builder-help-files?hsLang=en#interpreting-data) - [Product Search Help Files](https://help.fluorofinder.com/product-search-help-files?hsLang=en) - [Dye Directory Help Files](https://help.fluorofinder.com/dye-directory-help-files?hsLang=en) - [Cell Types Tool Help Files](https://help.fluorofinder.com/cell-types-tool-help-files?hsLang=en) - [Inventory Help Files](https://help.fluorofinder.com/inventory-help-files?hsLang=en) - [Training Help Files](https://help.fluorofinder.com/training-help-files?hsLang=en) - [Groups and Sharing](https://help.fluorofinder.com/groups-and-sharing?hsLang=en) - [Advanced tips and tricks](https://help.fluorofinder.com/advanced-tips-and-tricks?hsLang=en) - [Trouble Shooting](https://help.fluorofinder.com/trouble-shooting?hsLang=en) - Home - Products - Pricing - Blog - Company # FluoroFinder fluorofinder.com Help Center Copyright © 2026, FluoroFinder
