Streptavidin binds to biotin with high affinity. DyLight™ 488-conjugated Streptavidin is useful for detecting biotinylated antibodies. The excitation of DyLight™ 488 by 493 nm laser light induces a fluorescence emission maximum of 518 nm.
This streptavidin product is quality control tested by immunofluorescent staining with flow cytometric analysis. The concentration provided is based upon molecular mass of streptavidin independent of any additional molecular mass that might be added by the DyLight™ 488 conjugation. It is recommended that the reagent be titrated for optimal performance for each application.
