Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation: Streptavidin is conjugated with Spark YG™ 593 under optimal conditions
Concentration: 0.5 mg/mL (concentration relates to the Streptavidin only component of the conjugate)
Storage & Handling: The streptavidin-Spark YG™ 593 solution should be stored undiluted between 2°C and 8°C, and protected from exposure to light. Do not freeze.
Application: FC - Quality tested
Recommended Usage: Each lot of this Streptavidin-Spark YG™ 593 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 YG™ 593 conjugation. For immunofluorescent staining, the recommended use of this reagent is ≤ 0.125 µg per 106 cells in 100 µL staining volume. It is recommended that the reagent be titrated for optimal performance for each application. * Spark YG™ 593 has a maximum excitation of 573 nm and a maximum emission of 593 nm.
Excitation Laser: Green Laser (532 nm)/Yellow-Green Laser (561 nm)
Application Notes: Streptavidin-Spark YG™ 593 is useful as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. The average molecular weight of Streptavidin-Spark YG™ 593 is 60 kD and Streptavidin alone is 52 kD.
