Mix-n-Stain™ CF® Dye Antibody Labeling Kits
Label your IgG antibody with one of our superior CF® Dyes in as little as 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

Overview of the Mix-n-Stain™ Antibody Labeling Kit workflow.
SEC-purified MCF-7-derived exosomes were stained with CD9 monoclonal antibody (CD9/2343) labeled with CF®488A using a Mix-n-Stain™ kit (right). Specific staining was seen, compared with the same antibody in buffer (left). Exosomes were detected on a CytoFLEX LX flow cytometer in the FITC channel.
Flow cytometry of MCF-7 cells unstained (gray) or stained with CD9 monoclonal antibody (CD9/2343) labeled with CF®488A using a Mix-n-Stain™ kit (green).
Mouse anti-transferrin receptor antibody from (endosome and plasma membrane marker) was labeled using Lightning-Link® Rapid DyLight® Conjugation Kits from Novus Biologicals (left) or Mix-n-Stain™ CF® Dye Antibody Labeling Kits (right) according to manufacturers’ instructions. The CF® dye conjugates show higher signal and more specific staining compared the DyLight®conjugates when imaged using the same settings, due to the superior brightness of CF® dyes. The insets show the same field of view imaged with a higher gain setting.
Mix-n-Stain™ labeling can be performed on unpurified antibodies in ascites fluid. Top: HeLa cells stained with anti-tubulin antibody in ascited, detected with CF®488A secondary antibody (left) or directly labeled using CF®488A Mix-n-Stain™ (right). Bottom: rat optic nerve cryosections stained with anti-GFAP (glial marker) detected with CF®568 secondary antibody or directly labeled with Mix-n-Stain™ CF®568. antibodies in Mix-n-Stain™ labeled ascites show comparable specificity to unlabeled antibodies detected using secondary antibody.
Monoclonal mouse anti-tubulin clone DM1A in ascites or purified in PBS with 1% BSA was labeled with CF®488A Mix-n-Stain using the modified protocol for total protein labeling. The Mix-n-Stain antibodies performed comparably in immunofluorescence staining of HeLa cells as unlabeled antibody (in ascites) detected with secondary antibody.
Rat testis with mouse anti-tubulin and CF®488A goat anti-mouse (min x rat) (green), CF®555 Mix-n-Stain labeled mouse anti-ZO1 (tight junctions, red) and CF®640R phalloidin (cyan).
HeLa cells stained with CF640R Mix-n-Stain labeled mouse anti-tubulin antibody (red). Actin filaments are stained with CF488A phalloidin (green). Mounted in Everbrite Mounting Medium with DAPI (nuclei, blue).
Mix-n-Stain™ labeling in the presence of 10-fold excess BSA or gelatin to IgG
by weight using the modified Mix-n-Stain™ protocol. Mouse anti-transferrin receptor IgG
or mouse IgG isotype control from BD Pharmingen were labeled using CF647 Mix-n-
Stain™ kits. Intracellular staining of Jurkat cells was analyzed in channel FL3 of a BD
FACSCalibur flow cytometer. Antibodies labeled in the presence of stabilizer showed
comparable signal to noise ratio compared to conjugates labeled without stabilizer.
A. Graph shows the geometric mean fluorescence of the cell populations. B. Graph
shows signal to noise ratio (anti-TfR fluorescence/isotype fluorescence).
Comparison of Mix-n-Stain™ CF®647 labeling of anti-TfR antibody (endosome and cell surface marker) in HeLa cells without added protein compared to 1% BSA or 1% gelatin (10-fold excess) using the modified protocol for labeling in the presence of stabilizer protein. Labeling using the modified protocol gives comparable results as the standard protocol, with bright signal and minimal increase in non-specific background.

Unrivaled Convenience
Mix-n-Stain™ labeling tolerates common antibody buffer formulations. An ultrafiltration centrifuge vial is provided to quickly remove interfering substances like glycerol, or to concentrate your antibody. With a slight modification in protocol, antibodies can be labeled in the presence of BSA, gelatin, or ascites fluid. Because CF® Dyes are highly water soluble, the presence of other proteins like BSA or gelatin in the labeling reaction has minimal effect on background fluorescence, because any labeled non-antibody proteins readily wash away during immunofluorescence staining.
Superior CF® Dyes
These kits feature a choice of 31 of Biotium's next-generation CF® Dyes, which were designed for advantages in brightness and photostability compared to other commercially available fluorescent dyes. Learn more about CF® Dyes.
Choose the Right Labeling Kit for Your Antibody
Mix-n-Stain™ Antibody Labeling Kits are very simple to use (see the workflow overview above). But before you begin, you must check that your antibody meets the compatibility requirements for labeling, and choose the right labeling protocol. Download the updated and expanded Product Protocol for a labeling check list to help you select the right kit size and labeling protocol for your antibody. Also see our Kit Compatibility and Protocol Selection Flowchart.
See the product table below for a quick reference of the maximum excitation and emission of each CF® Dye, or see our CF® Dye Brochure for more detailed dye information.
Other Labeling Kits
We now offer Mix-n-Stain™ Maxi Antibody Labeling Kits for labeling 1 mg of IgG antibody with CF® Dyes, as well as Mix-n-Stain™ CF® Dye IgM Antibody Labeling Kits and Mix-n-Stain™ Nanobody Labeling Kits.
