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 PE/Fire™ 640 conjugation. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
* PE/Fire™ 640 has a maximum excitation of 566 nm and a maximum emission of 639 nm. - Excitation Laser
