Avidin D, Fluorescein labeled, is made from our highly purified Avidin D by a special labeling technique. This product has an optimal fluorochrome to protein ratio and is the reagent we recommend for routine immunofluorescence applications. Compared to conventional primary and secondary fluorescent labeling techniques, Fluorescein Avidin D can provide greater sensitivity and lower background staining.
