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 green fluorescent dye CF488A. CF488A is a superior alternative to the traditional green fluorescent dye FITC (or fluorescein) owing to its exceptional brightness and photostability. CF488A has brightness and photostability comparable to Alexa Fluor? 488.
