Mix-n-Stain™ antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your antibody with biotin or one of our superior CF™ dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. Choose from kit sizes to label 5-20 ug, 20-50 ug, or 50-100 ug of your antibody. For more information and guidelines for selecting a kit size, please download the Mix-n-Stain™ flyer and the product information sheet for this product. This kit is for labeling an antibody with far-red fluorescent CF™660C. CF™660C is a cyanine-based dye engineered to be highly water-soluble without being excessively charged. As a result, CF™660C-antibody conjugates have high signal-to-noise ratio in immunostaining. CF™660C is several fold brighter and significantly more photostable than Alexa Fluor® 660. CF™660C absorbs at 667 nm but can still be sufficiently excited by the 633 or 635 nm laser with emission at 685 nm in the borderline spectral region between far-red and near-IR fluorescence.Compatible with the NucleoCounter® NC-3000™.
