Polyclonal anti-FLAG (DYKDDDDK) is designed to detect FLAG tagged fusion proteins. The antibody recognizes the epitope tag fused to either the amino- or carboxy- termini of targeted proteins. This product is prepared by labeling high quality polyclonal rabbit anti-FLAG IgG (H+L) with the orange fluorescent dye CF™543. CF™543 is an orange fluorescent dye with an excitation spectrum optimally matching the 543 laser line. Antibody conjugates of the dye are much brighter than those of Alexa FluorÐ² 546.Compatible with the NucleoCounter® NC-3000™.
