Avidin D, Fluorescein labeled, having an excitation at 495nm and an emission at about 515nm, is made from highly purified Avidin D by a special labeling technique. High fluorochrome to protein ratio and is the reagent we recommend for routine immuno-fluorescence applications. Compared to conventional primary and secondary fluorescent labeling techniques, Fluorescein Avidin D can provide greater sensitivity and lower background staining.
