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 orange fluorescent CF™543. CF™543 has an excitation spectrum optimally matching the 543 nm laser line. Antibody conjugates of the dye are much brighter than those of Alexa Fluor® 543.Compatible with the NucleoCounter® NC-3000™.
