Mix-n-Stain is a revolutionary antibody labeling technology that allows you to label antibodies with our superior CF dyes, FITC, or biotin in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. For more information, please download the Mix-n-Stain flyer and the product information sheet for this product.

The optimal antibody concentration for labeling is 0.5-1 mg/mL. The kit includes an ultrafiltration microcentrifuge vial that can be used to concentrate antibody solutions prior to labeling. For quantitating antibodies of unknown concentration, Biotium offers the AccuOrange Protein Quantitation Kit, a highly sensitive fluorescence-based protein assay in 96-well format.

For larger scale labeling of proteins with one of our CF Dyes or biotin, our SE Protein Labeling Kits include everything you need for 3 X 1 mg protein labelings, with fast and easy purification using microcentrifuge ultrafiltration vials.

For labeling antibodies for small animal imaging, please see our VivoBrite CF680 Kit.
