Mix-n-Stain™ CF® Dye Small Ligand Labeling Kits

See our CF® Dye Quick Reference Table for a list of dyes and summary of their features. Our CF® Dye Selection Guide has more detailed information on each CF® dye, and ordering information for our various CF® dye product lines. You can download CF® dye normalized absorption and emission data in Excel format.

For CF® dye, cyanine dye, FITC, biotin, DNP, and dig kits, see the Mix-n-Stain™ Kit Compatibility and Protocol Selection Flowchart, below. We also recommend downloading the updated Product Protocol and completing the pre-labeling checklist to find the right protocol and kit size to use for each antibody you wish to label. Learn more about CF® dyes on our CF® Dye Technology Page, or download the CF® Dye Brochure.

Note that Mix-n-Stain™ Maxi 1 mg Scale Kits, Mix-n-Stain™ Fluorescent Protein Labeling Kits (R-PE, APC, PerCP, or tandem dye), Mix-n-Stain™ Enzyme Labeling Kits (AP, HRP, GOx) have different compatibility requirements and labeling protocols. Check the protocol for your kit to verify that your antibody is compatible with labeling, then choose a kit size that matches your the amount of antibody you wish to label.

CF® Dyes are highly water soluble, small organic dyes designed by scientists at Biotium for labeling proteins and nucleic acids. With a series of over 35 colors (and growing), many of our CF® Dyes are brighter and more photostable than competing dyes. For more information please see the product flyers for individual CF® Dyes, the CF® Dye Selection Guide, and our CF® Dye FAQs.

See below for our recommended alternatives to Akoya tyramides. Unless noted as a direct replacement, these tyramide dyes are spectrally similar alternatives. They have not been validated as direct replacements for use with Akoya kits or imaging systems.

The exact chemical structures of CF® dyes are currently confidential but will be fully disclosed at a later stage when pending patents become granted. In general terms, the structure of a CF® dye may be divided into two parts: a) dye core structure (i.e. the aromatic ring skeleton that defines the dye’s color or absorption/emission wavelengths), and b) core structure-modifying elements. At present, CF® dyes bear the core structures of coumarin, pyrene, rhodamine or cyanine dyes. Blue fluorescent CF® dyes are based on coumarin or pyrene dye core structure, while green to near-IR CF® dyes are based on either cyanine or rhodamine dye core structures. Core structure-modifying elements refer to various chemical attachments to the core structure and are a key aspect of the CF® dye invention that makes CF® dyes superior to other commercial dyes.
