Recommended Usage

Each lot of this Streptavidin-Spark UV™ 387 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 Spark UV™ 387 conjugation. For immunofluorescent staining, the recommended use of this reagent is ≤ 1 µg per 106 cells in 100 µL staining volume. It is recommended that the reagent be titrated for optimal performance for each application.

* Spark UV™ 387 has a maximum excitation of 351 nm and a maximum emission of 387 nm.
