Product Description

Mix-n-Stain™ CF® Dye Antibody Labeling Kits allow you to label ≤5 ug up to 100 ug of your antibody in just 30 minutes, with minimal hands-on time and no purification.

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 29 of Biotium’s next-generation CF® dyes, which were designed for advantages in brightness and photostability compared to Alexa Fluor®, DyLight®, and other 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.

We now offer Mix-n-Stain™ Maxi Antibody Labeling Kits for labeling 1 mg of antibody with CF® dyes, and Mix-n-Stain™ Nanobody Labeling Kits. Mix-n-Stain™ kits also are available for labeling antibodies with enzymes (HRP, AP, and GOx), fluorescent proteins (PE, APC, PerCP, and tandem dyes), biotin, or DIG. See our full selection of Mix-n-Stain™ Antibody Labeling Kits.
